Étiquette : MOTION UNDER GRAVITY
-
A ball is thrown upwards from the ground with an initial velocity ‘u’.The ball is at a height of 60 m at two times,the interval being 6 s.Find the initial velocity ‘u’
Solution: First Method: The ball reaches the given height of 60 m at a time t 1 seconds ( rising up).For the second time it reaches the 60 m height at a time t 2 seconds. (comes down) Applying the equation of motion with the sign convention. Initial velocity (u) = +u Acceleration due to…
