Question

How far can a mother push a 20.0 kg baby carriage, using a force of 62.0 N at an angle of 30.0º to the horizontal,
if she can do 2920 J of work?

Answer 1

have a look at the image

The work done by the mother in pushing the carriage is equal to: where F is the force applied d is the displacement of the carriage is the angle between the direction of the force and the displacement In this problem, we have the following data: is the force is the work done is the angle between the direction of the force and the displacement Re-arranging the equation above and substituting data, we find the displacement:
