Question

A miniature hill in a child’s toy collection is shown below. When released at A, a mass m slides down the path shown below, reaching the bottom (B) with a speed of v_B. Assume that the hill has negligible friction. The block then slides along the rough horizontal surface a distance d before coming to rest at C.

When solving parts (a) and (b):

Write the useful description about what is known and unknown.
Write down the physics principle or strategy you will use.
Symbolically solve for the unknowns

(a) Calculate the height of the hill using m=230.0 g and v_B= 3.8 m/s

(b) What is the coefficient of kinetic friction along the horizontal surface if d=14 m?

Hint: Treat the motion down the hill and the motion down the rough horizontal surface as two distinct problems. What physics concepts can you apply for each?
