Energy, Work and Power
 

Energy, Work and Power problem 83


A worker pushes a cart weighing 15 kg up a slope. The cart moves straight evenly, and the braking forces are neglected. The worker pushes with a force of 107 N, which is parallel to the direction of movement of the cart, and in doing so performs 375 J of work.


Force applied on the cart and the height change



  • How far does the cart travel?

  • Calculate the height change of the cart.
