A bowling ball has a mass of 9.0 kg,a moment of inertia of 3.6 × 10−² kg·m²,and a radius of 0.10 m.If it rolls down the lane without slipping at a linear speed of 3 m/s,what is its angular speed? A) 90 rad/s B) 30 rad/s C) 27 rad/s D) 0.030 rad/s E) 0.090 rad/s

Question

Quizplus · Accepted Answer

The angular speed ω can be found using the relationship v = ωr, where v is the linear speed and r is the radius. Thus, ω = v/r = 3 m/s / 0.10 m = 30 rad/s.
