Exercise 10.22 2

A hollow, spherical shell with mass 2.45 kg rolls without slipping down a slope angled at 30.0 ∘.

Part A

Find the acceleration.

Take the free fall acceleration to be g = 9.80 m/s2

Part B

Find the friction force.

Take the free fall acceleration to be g = 9.80 m/s2

Part C

Find the minimum coefficient of friction needed to prevent slipping.
