A 62.00 kg person in a 33.00 kg cart is coasting with a speed of 15 m/s before it goes up a hill.

assuming there is no friction, what is the maximum vertical height the person in the cart can reach?

Respuesta :

Answer:

11.47 m high

Explanation:

All of the Kinetic Energy converts to Potential energy

1/2 m v^2 = mgh      divide both sides by 'm'

1/2 v^2 = gh                (note that the masses given are irrelevant !)

(1/2 v^2) / g = h

(1/2 (15^2) / 9.81 = h     = 11.47 m
