Question

4.8m4.5mА2.0m1. An ice block on a frictionless path starts at rest and is released on the path. At the top of the path, the block obviously has GPE, how much GPE does ithave at point A when it starts at rest?

Answer 1

Answer:

The ice block has a GPE of 0 Joules at point A

Explanations:

Gravitational Potential Energy (GPE).

The amount of GPE an object on Earth depends on its mass and height above the ground.

GPE = mass x gravity x height

At point A, the height of the ice block = 0 (since it is at rest)

That is height = 0

Therefore:

GPE = mass x gravity x 0

GPE = 0 Joules
