Abaseball has a mass of 0.15 kg and radius 3.7 cm. in a baseball game, a pitcher throws the ball with a substantial spin so that it moves with an angular speed of 50 rad/s and a linear speed of 48 m/s. assuming the baseball to be a uniform solid sphere, determine the rotational and translational kinetic energies of the ball.

Rotational kinetic energy is 0.513 j

Transnational kinetic energy is 172.8 j                      

Explanation:

We have given mass of the baseball m = 0.15 kg

radius r = 3.7 cm = 0.037 m

Angular velocity is given as

Linear velocity v = 48 m/sec

We know that moment of inertia is given by

Now rotational kinetic energy is given by

Now transnational kinetic energy is given by
