Answer to Problem 18SSC

  W=3.46kJ

Explanation of Solution

Given:

Mass of the refrigerator is m=185kg .

Length of ramp is l=10m .

Angle of ramp is θ=11o .

Formula used:

Work done can be obtained by:

  W=Fd

Where, F is force applied, W is work done and d is displacement along force.

  Glencoe Physics: Principles and Problems, Student Edition, Chapter 10.1, Problem 18SSC

The component of mg along plane is mgsinθ as shown above.

As the plane is frictionless and refrigerator is moved slowly with constant velocity, it means that there is no net force parallel to ramp on refrigerator.

So, force parallel to plane will be

  F=mgsinθ

So, work done is

  W=mgsinθ×d=185×9.8×sin11°×10=3.46kJ

Conclusion:

Therefore, work done by mover on the refrigerator is W=3.46kJ .
