Question

mia places her backpack, which has a mass of 4 kg on a shelf that is 2 meters high. how much gravitational potential energy does the backpack on the shelf?

Explanation:

Step1: Recall the formula for gravitational potential energy

The formula for gravitational potential energy is \(U = mgh\), where \(m\) is the mass, \(g\) is the acceleration due to gravity (\(g = 9.8\space m/s^{2}\)), and \(h\) is the height.

Step2: Substitute the given values into the formula

Given \(m = 4\space kg\), \(h=2\space m\), and \(g = 9.8\space m/s^{2}\).
