A bowling ball has a mass of 7.00 kg,a moment of inertia of 2.8 × 10−² kg·m²,and a radius of 0.100 m.If it rolls down the lane without slipping at a linear speed of 4.30 m/s,what is its angular speed? A)70.0 rad/s B)43.0 rad/s C)30.1 rad/s D)0.430 rad/s E)0.700 rad/s

Question

Quizplus · Accepted Answer

The angular speed ω can be found using the relationship between linear speed v and angular speed: v = ωr. Solving for ω gives ω = v/r = 4.30 m/s / 0.100 m = 43.0 rad/s.
