3. In 2. A 7.5-kg otter slides down a hill, starting from rest at the top. The sloping surface of the hill is 8.8 m long, and the top is 6.5 m above the base. If the speed of the otter at the bottom of the hill is 9.2 m/s (a) how much energy was lost to nonconservative forces on the hill? (5 points) (b) what would be the speed of the otter at the base if there was no energy loss? (5 points) (C) if the energy loss was due to friction, what is the work of the frictional force? (5 points) (d) if the force of friction at the ground is 5.3N, what distance will the otter cover from the base to the end of her journey, before she stops moving? (hint: use the work) (5 points)
