foreign foreign horizontally foreign the main feature of scenario two is that the projectile is launched horizontally the key features is listed below Kiki since the projector is launched horizontally initially there is no vertical motion therefore initial Vertical Velocity is zero initial particular velocity number zero since physical is launched horizontally the horizontal velocity Remains the Same throughout the motion by the way AC pointable now is it only applicable for scenario two plus a Quantum no there is applicable for all the scenarios of positive motion horizontal vertical sorry horizontal velocity foreign calculate how far the Cannonball lands after being launched questionable so diagram key executives velocity 12 meters 10 meters okay 11 questions of the times guys zero subscribe s equals to UT plus half H is s equals u t plus half a t squared to that very equal to a SL value is 0 plus half a t Square guys 9.81 minus sign forward minus okay foreign diamond everyone one more time there is one quantity that is common for both horizontal and vertical aspects of projectile motion and that quantity is time time is common for both horizontal and verticals everyone all right so foreign foreign foreign please subscribe foreign do you have said foreign this is 17. 17.19.2 okay what do you think because let's see exactly all good everyone guys absolutely no problem be very honest with me um absolutely fine guys please nothing else absolutely no pressure at all confusing anyone else please raise your hands okay projectile motion number one responsibility projectile motion and number one responsibility calculations and horizontal separate from one another Okay so foreign 10 equals to half nine point eight one into tier value 1.43 1.43 seconds horizontally so let's see what's going on horizontally let's see what's going on horizontally everybody horizontally equation Willow speed equals to Distance by times it goes to speed into Times speed into time 1.43 7.16.2 units this is the idea now 99 of the times this is everyone 99 percent this is the format distance check this out question number eleven first question in section B project exactly foreign related everyone today I mean a green arrow turkey are whatever these are my components incredible make sure okay anyway so these are the components and this is the actual velocity is this is the question everyone Jay they asked me to calculate a velocity Green Arrow mode using these two components so actor component already horizontal I already know the value of this horizontal component everybody what is the value K 12 guys foreign foreign foreign 14 meter per second absolutely what about that everyone 's horizontal component about everybody horizontal componential 12 are HMR vertical componential or seen everyone H over 12 8 Mr 14. guys 12 or 14. actual velocity over here can I not construct a vector triangle right so ETA use Square I can construct a vector triangle Vector triangle a this will be my horizontal this is my vertical and this will be the resultant foreign 14. 12. there are 14 square plus 12 square root over answers at in point four fine there is your resultant 18. something that is your resultant but you might be wondering everybody calculate the speed calculate the velocity foreign equals to opposite by and the central law 12. right 14 by 12 shifts 10 answers 49.4 by 49 problem actual velocity 18.4 18.4 meter per second take your time everybody I will not be doing that for you excuse me when it comes to velocity velocity is a vector quantity which deals with both magnitude and Direction magnitude 18.4 and direction to the horizontal that's why we have to find out Theta is let me know when you're done foreign from a height of this Asian guy I'm a total displacement and value total distance clear now everyone okay next question throughout the motion particular direction a is it double motion or single motion double motions everybody all right you can think of scenarios free to be a combination of one and two synonyms here the most important concept to consider is the total vertical displacement projectile lands below the point of launch position since there are two directions involved in the direction of support and downward total vertical expression would be minus H total vertical discussion about minus h the rest of the ideas remain the same total vertical discussion minuses next foreign foreign foreign foreign [Music] foreign 30. everybody 15. meter per second day at an angle of degree conditions at an angle of 30 degree this angle is 30 degree a15l horizontal component guys or vertical component available 15 sine 30 about a year value 15 sign 13. aircel value minus eight correct yes minus 9.81 um foreign minus eight minus eight equals to You Got Away fifteen sine 30 minus 9.81 divided by 2 x 4.905 minus 4.905 T Square guys 4.905 T Square minus 15 sine 30 T minus 8 equals to 0 go to your calculator go to equation equation L uh degree 2. air value hello 4.905 minus 15 sine Thirty or minus eight do the value is foreign minus 15 sine 30 or C Hollow minus eight X evaluation or minus a is that is your answer two point two five seconds calculate how far the ball lands from the edge of the cliff guys I literally have only and only one equation spin equals to Distance by time so what is my distance right foreign equals to Distance by time the distance away speed into time speed hello 15 cos 30 into time is 2.25 29 .2 8 228 so 329 29.29.2 unit let's check everybody let's check the average okay wasn't without that ball 29.2 meters 29.2 meters eight meter is eight uh at a speed of one five that is one two three four exactly on the spot and everything is correct everybody all right calculate the velocity is similar to a calculation time can you do the same thing for me with this part right the same is quick find out the vertical for me quickly guys are online literally half of the class is doing the class online again thank you foreign let's get back out so vertically everyone vertically questions V squared equals to U squared plus twice a s l a v square equals to U comma vertically 15 cos sine I mean the vertical Direction 15 sine 30 put a whole Square minus 2 into 9.81 into s cathode minus 8 regular 15 sine 30 squares away Plus 2 into 9.81 into 8. root over answer 14.6 14 .6 okay I just found out the particle one particular value hello 14.6 30. is equal to 12.99 12.99 14 .6 Square plus 12.99 square root over answers 19.5 minutes long foreign thank you 48.3 48.3 48 degree this is your answer there is foreign
