A crazy road near your home, called “Dead Man’s Grade”, involves a 100 m long slope followed by a 20 m drop. The road has long been closed due to many accidents. You and your friends like to push your 25 kg go-cart up the backside of the grade and coast down the steep slope.
a. How much force is needed to push the go-cart up the hill?
b. What speed will the go-cart reach at the bottom of the hill? Neglect regarding forces.
