Question

A horizontal force of 2.0 N is applied for 3.0 seconds to a block on an icy surface. The 1.5 kg block is initially at rest.

A) What is the final velocity?

B) The block then slides through an icy path:

Down a 10.0 m tall incline

Completely around a 1.5 m radius loop-de-loop

Up a 3.0 m tall incline

What is the speed after the incline?

C) (Similar to part A...) Horizontally push a sphere at its center of mass with a force of 2.0 N. Sphere is uniform, of mass 1.5 kg and radius .05 m. Find its linear speed after 3.0 seconds, starting at rest, no slipping.
