You want to throw a 0.145 kg baseball with a speed of of 144 km/hr. To achieve that, you swing your hand so that the displacement of the ball is 2.20 m and release it. Assuming that the force during the swing is constant, find the magnitude of the force.

Solution:
Work done by person to release the ball:
All work done is transferred in form of kinetic energy
Velocity of ball is 144km/h converting to m/s
Hence energy of ball is: Now we have Hence...
