Question

calculate the energy

Answer 1

Answer:

8550 Joules of energy.

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
