Question

a sled is at rest at the top of a slope 2 m high. the sled has a mass of 45 kg. what is the sleds potential energy? (formula: ( pe = mgh ))

Explanation:

Step1: Substitute the values into the formula

Given \(m = 45\space kg\), \(g= 9.8\space m/s^{2}\), \(h = 2\space m\).
The formula for potential energy is \(PE=mgh\).
Substitute the values: \(PE=(45)(9.8)(2)\)

Step2: Calculate the product

First, calculate \(45\times9.8 = 441\).
Then, \(441\times2=882\)

Answer:

\(882\space J\) (Option D)
