Question

1. a 60 kg skier stands 50 meters above the base of a slope. what is her potential energy? 29,400 j 3,000 j 59,000 j 6,000 j

Explanation:

Step1: Recall the formula for potential energy

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

Step2: Substitute the given values into the formula

Given \(m = 60\ kg\), \(h=50\ m\), and \(g = 9.8\ m/s^{2}\). Then \(U=(60\ kg)\times(9.8\ m/s^{2})\times(50\ m)\).
First, calculate \(60\times9.8 = 588\), then \(588\times50=29400\ J\).

Answer:

29,400 J
