A cricket ball of mass 150 g is moving with a velocity of 12 m/s and is hit by a
bat so that the ball is turned back with a velocity of 20 m/s. The duration of
contact between the ball and the bat is 0.001 s. In hitting a ball, time of contact is
small so that large force acts on the ball produces greater acceleration
(i) The change in the linear momentum is:
(a) 7.4 N (b) 4.8 N (C) 1.2 N (d) 5.7 N
(11) Average force exerted by the bat is:
(a) 480N
(b) 120 N
(C) 840 N (d) 1200N
(111) The retardation of the ball is:
(a) 1600 ms
(b) 320 ms (c) 3200 m/s (d) 160 m/s2
(iv) Inertia of a body in linear motion is measured by its:
(a) velocity (b) momentum (c) mass
(d) none of these
(v) SI unit of momentum is.
