Question

A 48 kg cart is sitting motionless at the top of the hill. At what height, did the cart start at, to reach 88435 J of energy at the end of the ride? Group of answer choices 19 meters 456 meters 188 meters 0.19 meters

Answer 1

Answer : The height is 188 meters

Explanation : When the cart reached at the end from top of hill then the cart have potential energy .

Given that,

Potential energy = 88435 J

Mass of cart = 48 kg

We know that,

The potential energy is

`mgh =88435`

`h= (88435)/(48*9.8)`

`h = 187.9 = 188\ meters`

So, the height of the top is 188 meters.
