Textbook Problem

A child and a sled with a combined mass of 50.0 kg slide down a frictionless slope. If the sled starts from rest and has a speed of 3.00 m/s at the bottom, what is the height of the hill?

To determine
The height of the hill.


Given Info:

Combined mass of the child and sled is 50.0kg .

The speed of the sled at the bottom is 3.0m/s .

Since the sled is sliding down on a frictional less surface and no other non conservative forces are doing work. Consider the zero potential energy at the base of the hill.

According to conservation of mechanical energy,

12mvf2+mghf=12mvi2+mghi       (I)

  • m is the mass of the child and the sled
  • vf is the final velocity of the system
  • g is acceleration due to gravity
  • hf is the final height with base of the hill
  • vi is the initial velocity of the system
  • hi is the initial height of the system

Since the child is sling to the bottom of the hill,


Equation (I) gives,
