Question

From an apple tree 2 metres high, a 100g mass apple fell of the tree, what work did it do?

Answer 1

Answer:

Workdone = 1.96 Nm

Explanation:

Given the following data;

Mass = 100g to kg 100/1000 = 0.1Kg

Distance = 2m

To find the workdone;

First of all, we would determine the force acting on the apple

Force = mass * acceleration due to gravity

But, acceleration due to gravity is equal to 9.8m/s²

Force = 0.1 * 9.8

Force = 0.98N

Now, we can find the workdone using the formula;

Workdone = force* distance

Substituting into the equation, we have

Workdone = 0.98 * 2

Workdone = 1.96 Nm
