The change in the skier's gravitational potential energy is 199430 J.
<h3> Gravitational potential energy:</h3>
This is the energy of a body due to its position in a gravitational field. The S.I unit of gravitational potential energy is Joules (J)
The Change in the skier's gravitational potential energy can be calculated using the formula below.
Formula:
- ΔP.E = mg(Δh)............... Equation 1
Where:
- ΔP.E = Change in the skier's potential energy
- m = mass of the skier
- Δh = change in height to which it was raised
- g = acceleration due to gravity.
From the question,
Given:
Substitute these values into equation 1
- ΔP.E = 55×370×9.8
- ΔP.E = 199430 J.
Hence, The change in the skier's gravitational potential energy is 199430 J.

You don't need to do any calculations, you are already given that n=1.5
n is index of refraction. it's 1.5
Answer:
This is the simplified definition.
Explanation:
The main goal of physics is to explain how things move in space and time and understand how the universe behaves.
D= vt +.5at^2
since he started at rest, v (initial velocity) is 0
so d=.5at^2
d = .5 (6m/s^2) (4.1s)^2
then put that into a calculator.
