PLEASE HELP ME (JOULES)

Type the correct answer in the box. Round your answer to the nearest whole number.
Dina has a mass of 50 kilograms and is waiting at the top of a ski slope that’s 5 meters high.
The maximum kinetic energy she can reach when she skis to the bottom of the slope is
joules.
Use PE = m × g × h and g = 9.8 m/s2. Ignore air resistance and friction.

Answer:

The answer is not 9.9 i used that and got it wrong

Explanation:

Answer:

2450 joules

Explanation:

The formula for potential energy is PE = m x g x h

m is the mass, in kg (50)

g is the acceleration due to gravity, in meters per second squared (9.8)

h is the height, in meters (5)

The problem gives m = 50, g = 9.8, and h = 5. Plug that into the formula and get the answer.

[tex]PE = mgh\\PE = (50) (9.8) (5)\\PE = 2450[/tex]
