Question

1. a toddler is sitting on top of a hill that is 20 m high. the toddler has a weight of 15 n. how much gravitational potential energy does the toddler have?

Explanation:

Step1: Recall the formula for gravitational potential energy

The formula for gravitational potential energy \(U = mgh\). But since weight \(W=mg\), the formula can also be written as \(U = Wh\).

Step2: Substitute the given values into the formula

We are given that \(W = 15\space N\) and \(h=20\space m\). Substituting these values into \(U = Wh\), we get \(U=(15\space N)\times(20\space m)\).

Answer:

\(300\space J\)
