An athlete with mass of 50kg runs up a hill. the foot of the hill is 400m above sea level and summit is 900m above sea level. calculate by how much the athlete's gravitational potential energy increases.

An athletic with a massage of 50 kg runs up a hill .the foot of the hill is 400m above sea level and the summit is 900m above sea level .calculate by how much the athlete 's gravitational potential energy increased.

yes

900-400=500

50kg*10m/s2*500

400 kJ

To calculate the increase in the athlete's gravitational potential energy, we need to find the difference in height between the foot and the summit of the hill.

The gravitational potential energy can be calculated using the formula:

Gravitational Potential Energy = mass * acceleration due to gravity * height

Given:
Mass of the athlete (m) = 50 kg
Acceleration due to gravity (g) = 9.8 m/s^2 (approximately)
Height difference (h) = 900 m - 400 m = 500 m

Substituting the given values into the formula:

Gravitational Potential Energy = 50 kg * 9.8 m/s^2 * 500 m

Calculating this expression will give us the increase in the athlete's gravitational potential energy.

mg(h2-h1) = 50*9.8*500

24 5000
