A cricket bowler releases tha ball in two different ways
giving it horizontal velocity and a small downward velocity and the speed `v_s` at the time of release is the same. Both are relased at a height H from the ground. Which one will have greater speed when the ball hits the ground? Neglect air resistance.

A cricket bowler releases the ball in two different ways (a) giving it only horizontal velocity and (b) giving it horizontal velocity and a small downward velocity. The speed v_s at the time of release is the same . Both are released at a height H from the ground . which one will have greater speed when the ball hits the ground ? Neglect air resistance.

Two balls of different masses (one lighter and other heavier) are thrown vertically upward with same initial speed. Which one will rise to the greater height)?

Two stones are thrown up simultaneously from the edge of a cliff 200 m high with initial speeds of 15 m s^-1 and 30 m s^-1 . Verify that the graph shown in Fig. 3.27 correctly represents the time variation of the relative position of the second stone with respect to the first. Neglect air resistance and assume that the stones do not rebound after hitting the ground. Take g = 10 m s^-2 . Give the equations for the linear and curved parts of the plot.

A bullet of mass m fired at 30^@ to the horizontal leaves the barrel of the gun with a velocity v. The bullet hits a soft target at a height h above the ground while it is moving downward and emerges out with half the kinetic energy it had before hitting the targtet. which of the following statements are correct in respect of bullet after it emerges out of the target?

A curved surface is shown in the figure. The portion BCD is free of friciton. There are three spherical balls of identical radii and masses. Balls are released from rest one by one from A which is at a slightly greater height than C. With the surface AB, ball 1 has large enough firction to cause rolling down without slipping, ball 2 has a small friction and ball 3 has a negligible frction. Which balls (s) can reach D?
