1. Mr. Mangan is standing at the edge of a cliff with a herd of buffalo running below him. Mr. Mangan wants to take out a buffalo by pushing a boulder off the cliff landing directly on top of the buffalo. The boulder has a mass of 100 kg and it is 1.5 m away from the cliff. The coefficient of kinetic friction between the boulder and the ground is 0.3. He applies 300 N of force to move the boulder. How much work was done by Mr. Mangan on the boulder to get it to the edge of the cliff? What was the net work done on the boulder? 2. The boulder imbles off the edge of the cliff and falls to the ground. If the cliff is 90 m tall, how much work was done by gravity on the boulder?
