A small ball is given some velocity at point A towards right so that it moves on the semicircular track and does not leave contact up to the highest point B. After leaving the highest point B, it falls at the top of a building of height R and width `x(xlt lt 2R)`. (All the surfaces are frictionless).

The velocity given to the ball at point A so that it may hit the top of the building is

What is the velocity of the projectile highest point ?

What is the velocity of a projectile at the highest point?

A ball is thrown in air . What are its velocity and acceleration at the highest point ?

A tennis ball is thrown upward at an angle from point A. It follows a parabolic trajectory and hits the ground at point D. At the instant shown, the ball is at point B. Point C represents the highest position of the ball above the ground. While in flight, how do the x and y components of the velocity vector of the ball compare at the points A and D?

In a circus, a rider rides in a circular track of radius 'r' in a plane. The minimum velocity at the highest point of the track will be
