Fig. shows an estimated force-time graph for a base ball struck by a bat. From this curve, determine (i) impulse delivered to the ball (ii) force exerted on the ball (iii) the maximum force on the ball.

A ball is throwm upword with an initial velcoity o f 100 ms^(-1) . After how much time will it retun ? Draw velcoity - time graph for the ball and find from the graph (i) the maximum height attained by the ball and (ii) height of ball after 15 s. take g = 10 ms ^(-2) .

Ram dropped a cricket ball of mass 700 g from the top of a tower and the ball takes 5 s to reach the ground. He then determined the maximum velocity of the body by taking acceleration of the ball as 10 m s ^(-2) find out the value of maximum velocity.

A ball B is suspended from a string of length l attached to a cart A, which may roll on a frictionless surface. Initially the cart is at rest and the ball is given a horizontal velocity v_(0) . Determine the maximum height reached by the ball.

cricket ball of mass 150 g is moving with a velocity of 12m//sec and is hit by a bat so that the ball is turned back with a velocity of 20 m//sec, the force on the ball acts for 0.01 sec, then the average force exerted by the bat on the ball will b

A ball is thrown upward with an initial velocity of 80 ms^(-1) . After how much time will it return to ground ? Draw velocity-time graph for the ball and find from the graph (a) the maximum height attained by ball and (b) height of the ball after 12 s . Take g=10 ms^(-2) .

A small ball of mass m and density rho is dropped in a viscous liquid of density sigma . Ather some time the ball falls with a constant velocity. Calculate the viscous force acting on the ball.

As shown in fig. two identical balls strike a rigid wall with equal speeds but a different angles of incidence. They are reflected back without any lose in speed. (a) Determine the direction of force exerted by each ball on the wall. (b) Determine the ratio of impulse imparted by the two balls on the wall in both cases.
