Abowling ball has a mass of 1.3 kg, a moment of inertia of 0.075088 kg · m2 , and a radius of 0.38 m. it rolls along the lane without slipping at a linear speed of 3 m/s. what is the total kinetic energy of the rolling ball? answer in units of j.

8.19 Joules

Explanation:

m = Mass of ball = 1.3 kg

I = Moment of inertia = 0.075088 kgm²

r = Radius of ball = 0.38 m

v = Linear speed = 3 m/s

Angular speed

The linear and rotational kinetic energy will give us the total kinetic energy

The  total kinetic energy of the rolling ball is 8.19 Joules
