Question

A solid sphere of uniform density starts from rest and rolls without slipping down an inclined plane with angle θ = 30°. The sphere has mass M = 8 kg and radius R = 0.19 m . The coefficient of static friction between the sphere and the plane is μ = 0.64. What is the magnitude of the frictional force on the sphere?

Answer 1

40N

Step-by-step explanation:

frictional force = mgsin©

frictional force = 8*10*sin30

frictional force = 8*10*0.5= 40N//
