Question

A 5.00 kg bowling ball is held 70.0cm above the ground. Determine its potential energy:
a) 34.3 Joules
b) 123 Joules
c) 3.43 x 103
Joules
d) 1.23 x 104
Joules

Answer 1

We can find the potential energy of the bowling ball from the formula:

$$PE = mgh = 5.0kg \cdot 9.8 \dfrac{m}{s^2} \cdot 0.7m = 34.3 J.$$

Answer:

$a) 34.3 J.$
