## Homework Statement

A child 1.52 meters tall pulled a 2.54 kg toy car for 10 meters. The car has a string attached to it, and when pulled creates a 25 degree angle from the horizon. If the string has a force of 123 N on it while being pulled, how much work did the child do?

## Homework Equations

work = force x displacement

## The Attempt at a Solution

W = (123 N)(10 m) cos(25 degrees) = 1114.8 J

is this correct? does the child's height have anything to do with the problem?
