Question

A hollow cylinder, a solid cylinder, a hollow sphere, and a solid sphere roll down a ramp without slipping, starting from rest. The ramp is 0.25 m high. All the objects have radius 0.035. What are their final speeds?

Please show what equation you used and what you plugged in...I am so lost!

Answer 1

I figured it out

Solid Cylinder: v = sqrt 4gh/3

Hollow Cylinder: v = sqrt gh

Hollow Sphere: v = sqrt (6/5)(g)(h)

Solid Sphere: v = sqrt (10/7)(g)(h)
