A 6.7 kg bowling ball is lifted 1.8 m into a storage rack. Calculate the increase in the ball's potential energy.
Question
A 6.7 kg bowling ball is lifted 1.8 m into a storage rack. Calculate the increase in the ball's potential energy.
Solution
To calculate the increase in the ball's potential energy, we can use the formula for gravitational potential energy, which is:
Potential Energy (PE) = mass (m) * gravity (g) * height (h)
Given in the problem, we have:
mass (m) = 6.7 kg height (h) = 1.8 m gravity (g) = 9.8 m/s² (approximate value on the surface of the Earth)
Substituting these values into the formula, we get:
PE = 6.7 kg * 9.8 m/s² * 1.8 m
PE = 118.044 Joules
So, the increase in the ball's potential energy is approximately 118.044 Joules.
