Work Physics Problems with Solutions

Example 1:

Let us consider the work example problem: A train covers a distance of 15 km and that the force is causing it to accelerate at a rate of 0.7 m/s². Calculate the work done?

Solution:

We can calculate force, work and distance using the given formula.

Work:

Force:

Distance:

Where, W =Work, F = Force, D = Distance

Substituting the values in the above given formula,

Work = 15 x 0.7 = 10.5 J

Therefore, the value of Work is 10.5 J.

Example 2:

Refer the below work physics problem with solution for a boy who uses a force of 30 Newtons to lift his grocery bag while doing 60 Joules of work. How far did he lift the grocery bags?

Solution:

Substituting the values in the above given formula,

Distance = 60 / 30 = 2 m

Therefore, the value of Distance is 2 m.

Example 3:

Refer the below work sample problem with answer for the baseball player who does 1234 Joules of work when hitting a baseball into field. The baseball reached 100 meters away. Calculate the force used to hit the ball?

Solution:

Substituting the values in the above given formula,

Force = 1234 / 100 = 12.34 N

Therefore, the value of Force is 12.34 N.
