A boy of mass 50 kg can jump up to a height of 1.5 m. Calculate the potential energy of the boy at the highest point.
Question
A boy of mass 50 kg can jump up to a height of 1.5 m. Calculate the potential energy of the boy at the highest point.
Solution
To calculate the potential energy, we can use the formula:
Potential Energy (PE) = mass (m) * gravity (g) * height (h)
Given in the problem:
mass (m) = 50 kg gravity (g) = 9.8 m/s² (approximate value on Earth) height (h) = 1.5 m
Substitute these values into the formula:
PE = 50 kg * 9.8 m/s² * 1.5 m
PE = 735 Joules
So, the potential energy of the boy at the highest point is 735 Joules.
