3. 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)
Answer
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
