Question

5. There is a bell at the top of a tower that is 45 m high. The bell's mass is 200 kg. The bell has energy. Calculate it.

45000


900000 J


9000 J


88200 J

Answer 1

Step-by-step explanation:

Since the bell is at rest in an elevated position, we can assume that it only has potential energy.

U=mgh is the formula for potential energy where U=potential energy, m= mass, g=acceleration due to gravity, and h=height.

Plug in known variables....

U=200kg*9.8m/s^2*45m

U=88200 joules of potential energy or letter D.
