Explanation:
We are given that
Length of ladder=2.7 m
Mass,M=11 kg
Coefficient of friction=
Mass of painter=8M
Distance from base=d
We have to find the magnitude of the normal force exerted by the floor on the ladder.
Normal force exerted by floor on the ladder=
Where
Normal force exerted by floor on the ladder=
The gravitational potential energy (G.P.E) of the ceiling fan is 712.95 Joules.
<u>Given the following data:</u>
- Mass of ceiling fan = 7.5 kg
- Height = 0.7 m
<u>Scientific data:</u>
- Acceleration due to gravity = 9.8
To calculate the gravitational potential energy (G.P.E) of the ceiling fan:
<h3>What is gravitational potential energy?</h3>Gravitational potential energy (G.P.E) can be defined as the energy that is possessed by an object or body due to its position (height) above planet Earth.
Mathematically, gravitational potential energy (G.P.E) is given by this formula;
<u>Where:</u>
- G.P.E is the gravitational potential energy.
- m is the mass of an object.
- g is the acceleration due to gravity.
- h is the height of an object.
Substituting the given parameters into the formula, we have;
GPE = 712.95 Joules.
