Question

a cricket player holds a cricket ball of mass 100 gram by moving is and backward by 0.75 M if the initial velocity of the body is 108 km per hour find the retarding force applied by the player

Answer 1

Conversion of kmph into mps

It comes to 30m/sec

Now using 3rd kinematics formula

You get is

30*30 = 2*0.75*a

900/1.5 = a

600 = a

Now force is equal = m*a

0.1*600 = 60N
