Question

1. a cart has a mass of 50 kg and is lifted 2 m above the ground. what is its pe? (hint: pe = m × g × h, use g = 10)

Explanation:

Step1: Identify the formula and values

We use the formula $PE = m\times g\times h$, where $m = 50$ kg, $g = 10$ m/s², $h=2$ m.

Step2: Substitute values into formula

$PE=50\times10\times2$.

Step3: Calculate the result

$PE = 1000$ J.

Answer:

1000 J
