A ball is thrown vertically upward from a ground with speed of `40 m//sec`.It collides with ground after returning. Find the total distance travelled and time taken during its bouncing.

A body is thrown vertically upwards from ground with speed of 10m//s . If coefficient of restitution of ground, e=1//2 . Find (a) the total distance travelled by the time it almost stops. (b) time elapsed (after the ball has been thrown) when it is at its subsequent maximum height for the third time.

A particle of mass 2m is dropped from a height 80 m above the ground. At the same time another particle of mass m is thrown vertically upwards from the ground with a speed of 40 m/s. If they collide head-on completely inelastically, the time taken for the combined mass to reach the ground, in units of second is:

A ball is thrown vertically upwards from the top of tower of height h with velocity v . The ball strikes the ground after time.

A ball is thrown vertically upwards with a speed of 9.8 m/s from the ground. Draw the x-t, v-t and a-t graph for its motion.

A ball is thrown vertically upwards from the ground. Work done by air resistance during its time of flight is

A ball is thrown vertically upwards from the top of a tower of height 60 m with a speed of 20 m//s. (i) The ball strikes the ground after 6 s (ii) The ball strikes the ground with speed 40 m//s (iii) The distance of ball above the ground after 5 s is 35 m The maximum height attained by ball above the ground is 80 m

A ball is thrown vertically upwards from a height of 40 m and hits the ground with a speed that is three times its initial seepd. What is the time taken (in sec) for the fall ?
