Answer:
8550 Joules of energy.
Step-by-step explanation:
- The bell is situated at the top of the tower, height = 45m
- Weight of the bell, F = 190 N
- The workdone by the gravitational force = F.hcos180°
- As a result, when the body is 45 meters above the earth, gravitational force (e.g., weight) works downward. As a result, the angle formed by the force and h = 180°.
- Therefore the workdone by the gravitational force = 190 × 45 × -1
= -8550 J
- Thus, potential energy = neg of workdone
- = -(-8550 J) = 8550 J
