A boy throws a ball with a velocity u at an angle theta with the horizontal. At the same instant he starts running with uniform velocity to catch the ball before it hits the ground. To achieve this he should run with a velocity of

A 150 g tenins ball coming at a speed of 40m/s is hit straight back by a bat to speed of 60m/s. The magnitude of the average force F on the ball, when it is in contact for 5ms is,

In a cricket match , a batsman hits a boundary 6 times out of 30 balls he plays . What is the probability that in a given throw, the ball does not hit the boundary ?

The following problems illustrate the effect of a time-dependent force of a large average magnitude which acts on a moving object only for a short duration. Such forces are called 'impulsive' forces. According to the impulse-momentum theorem, impulse delivered to a body is equal to the change of linear momentum of the body. A ball of mass 250 g is thrown with a speed of 30 m//s . The ball strikes a bat and it is hit straight back along the same line at a speed of 50 m//s . Variation of the interaction force, as long as the ball remains in contact with the bat, is as shown in Fig. After collision with the hard floor, the ball will bounce to a height

A golf player hits a golf ball of mass 100 g and imparts it a speed of 50 m/s. If golf stick remains in contact with the ball for 0.01 s, then the average force exerted by the golf stick on the ball.

From a point on a smooth floor of a room a ball is shot to hit a wall. The ball then returns back to the point of projection. If the time taken by the ball in returining is twice the time taken to reach the wall, find twice the time taken to reach the wall, find the coefficient of restitution between was and ball.

A cricket ball is seen to hit the bat first and the sound of hitting is heared a little later. Why?
