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.

a) Assuming no friction, what should the otter's speed be at the bottom?

b) If the speed of the otter at the bottom of the hill is 9.2 m/s, how much energy was lost to non-conservative forces on the hill?
