A spherical ball of mass `20kg` is stationary at the top of a hill of height `100m` , it rolls down a smooth surface to the ground , then climbs up another bill of height of `30 m` and final rolls down to a horizontal base at a height of `20 m` about the ground . The velocity attained by the ball is

A spherical shell of mass 20 kg is stationary at the top of a hill of height 100 m. It rolls down a smooth surface to the ground, then climbs up another hill of height 30 m and finally rolls down to a horizontal base at a height of 20 m above, the ground. The velocity attained by the ball is :

A spherical ball of mass 20 kg is stationary at the top of the hill of height 100 m . It rolls down smooth surface to ground then climb up another hill of height 40 m and finally rolls down to a horizontal base at a height of 15 m above the ground . The maximum velocity attained by a ball is ....... ( g = 9.8 m//s^(2))

A spherical ball of mass 2 kg is stationalry at the top of a hill of height 100 m. It rolls down a smooth surface to the ground, then cilimbs up another hill of height 30 m and finally rolls down on a smooth surface to a horizontal base at a height of 20 m abvoe the ground. What is the final velocity attained by the ball? (g=10m//s^(2))

A ball is thrown vertically upward with a velocity of 20 m/s. Calculate the maximum height attain by the ball.

A ball is thrown vertically upward with a velocity of 20 m/s. Calculate the maximum height attain by the ball.

A ball is thrown from the ground with a velocity of 20sqrt3 m/s making an angle of 60^@ with the horizontal. The ball will be at a height of 40 m from the ground after a time t equal to (g=10 ms^(-2))

A ball of mass 2 kg is projected horizontally with a velocity 20m/s from a building of height 15m. The speed with which body hits the ground is :

A ball of mass 2 kg is projected horizontally with a velocity 20m/s from a building of height 15m. The speed with which body hits the ground is :

A ball is thrown horizontally with a speed of 20 m//s from the top of a tower of height 100m velocity with which the ball strikes the ground is .
