A spinning cricket ball takes a curved path, Explain.

A tennis ball and a cricket ball, both are stationary. To start motion in them :

A uniform moving cricket ball is turned back by hitting it with a bat for a very short time interval. Show the variation of its acceleration with time. (Take acceleration in the back ward direction as positive).

The work done by a fielder when he takes a catch in a cricket match is negative. Explain

Two identical balls A and B lie on a smooth horizontal surface, which gradually merges into a curve to a height 3.2 m . Ball A is given a velocity of 10 m//s , to collide head-on with ball B , which then takes up the curved path. What is the minimum coefficient of restitution, e , for the collision between A and B in order that ball B reaches the highest point C of the curve.

(A) : A player lowers his hands while catching a cricket ball. (r) : Increase in the time of action of force, decreases the impulsive force.

Calculate the uncertainity in the position of a cricket ball of mass 150 g if the uncertainity in its velocity is 3.53 xx 10^(-24 ) ms^(-1)

Calculate the uncertainity in the position of a cricket ball of mass 150 g if the uncertainity in its velocity is 3.53 xx 10^(-24 ) ms^(-1)

A player throws a ball upwards with an initial speed of 30 m s^(-1) . How long does the ball take to return to the player's hands? ( Take g = 10 m s^(-2) )

A car takes a curved path on a flat road where the maximum frictional force is less than the centripetal force. What will happen to the car ?

A uniformly moving cricket balls is hit with a bat for a very short time and is turned back. Show that variation of its acceleration with time taking the acceleration in the backward direction as positive.
