A body is thrown upwards with speed u from a building of height h. Another body B is thrown downwards with speed u. They reach ground with speed  and  respectively. The relation between  and .

A ball A is thrown vertically upwards with speed u. At the same instant another ball B is released from rest height h. At times t, the speed of A relative to B is :-

Statement I: A body is thrown verticallyupwards. If air resistance is to be takeninto account, then the time duringwhich the body rises is greater than thetime of fall.Statement II: A body is thrown verticallyupwards and when it reaches half of itsmaximum height, its accelerationremains same

A body is thrown up with a velocity 40m𝑠-1. At same time another body is dropped from a height 40 m. Their relative acceleration after 1.3 seconds is

wo people stand on different floors of an outdoor stairway. One is 5 m above the ground and the other is 10 m above the ground. The person on the lower floor throws a ball upward with a speed of 8 m/s and the other person just drops hers. Ignoring air resistance, which ball hits the ground at a higher speed? Question 10Answera.The one that is thrown upwardb.They both hit the ground with the same speedc.The one that is dropped

A body released from rest falls with an acceleration of 9.81 m/s2. If the same body is thrown upward, and air resistance is negligible, its accelera­tion will be Question 11Answera.upward and greater than 9.81 m/s2b.downward and greater than 9.81 m/s2c.downward and less than 9.81 m/s2d.upward and equal to 9.81 m/s2e.downward and equal to 9.81 m/s2
