Question

A bell hanging at the top of a tower has 8,550 j of energy. If it has a mass of 20 kg find the height of the Bell

Answer 1

Answer:

42.75m

Explanation:

8550 = mgh

8550 =20×10×h

h=8550/200

=42.75m

Answer 2

The height of the bell hanging at the top of a tower is 43.62 m.

The given parameters;

• potential energy of the bell, P.E = 8550 J
• mass of the bell, m = 20 kg

The height of the bell is determined by using gravitational potential energy formula as shown below;

P.E = mgh

where;

h is the height of the bell

$h = \frac{P.E}{mg} \\\\h = \frac{8550}{20 \times 9.8} \\\\h = 43.62 \ m$

Thus, the height of the bell hanging at the top of a tower is 43.62 m.
