Question

On Earth, a child kicks a ball, with a mass of 0.75kg, into the air reaching a maxheight of 4.3 meters. What is the potential energy at the highest point?

Answer 1

★ The formula for potential energy:

⇝ Potential Energy = mgh

➳ m = mass

➳ g = gravitational field

➳ h = height

★ Solution:

Potential Energy = mgh

➳ m = 0.75 kg

➳ g = 9.8
`m/s^(2)`

➳ h = 4.3 m

Potential Energy = 0.75 x 9.8 x 4.3

➻ Potential Energy = 31.605 J
