You pull a wagon across a floor with a force of 25 N over a distance of 30 meters.
The handle of the wagon you are pulling on has an angle of 35 degrees above the horizontal.
a) How much work do you do on the wagon?
You now let your wagon roll down a frictionless slope from rest. The height of the slope is 5 meters, and the angle of the slope with the horizontal is 10 degrees. Assume the mass of the wagon is 10 kg.
b) What is the final velocity of the suitcase (hint: use the work-energy theorem).
