Question

1. a person climbs a 5 m ladder. their mass is 60 kg. what is their potential energy at the top? 900 j 300 j 2,940 j 5,880 j

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 \(m = 60\space kg\), \(h = 5\space m\), and \(g = 9.8\space m/s^{2}\).
