A man standing on the edge of the roof of a `20 m` tall building projects a ball of mass `100 gm` vertically up with a speed of `10 ms^(-1)`. The kinetic energy of the ball when it reaches the ground will be `[g = 10 ms^(-2)]`

A man standing on the edge of a roof of a 20 m tall building projects a ball of mass 100 g vertically up with a speed of 10 ms^(-1) and simultaneously throws another ball of same mass vertically down with the same speed. Find the kinetic energy of each ball when they reach the ground. (g=10 ms^(-2))

A ball is dropped a height h. The velocity of the ball when it reaches the ground is 10ms^-1 . Find h.

A ball is projected horizontally with a velocity of 5 ms^(-1) from the top of a tower of height 10 m. When it reaches the ground (g=10 ms^(-2) )

A 5 kg ball is thrown upwards with a speed of 10ms^-1(g=10ms^-2) Find the potential energy when it reaches the highest point.

A body is projected vertically up with a speed of 20ms^(-1) .The distance travelled by it in "3" seconds it (g=10ms^(-2))
