Explanation / Answer

(a)Describe the energy transformations that take place when askier starts skiing down a hill, but after a time is brought torest by striking a tree.
potential energy will be transformed to kinetic energy.
after striking the tree kinetic energy will become to heat energyand heat energy and sound energy.
(b)Why is it easier to climb a steep mountain via a zigzagtrail (switchbacks) than to climb straight up?
by following zigzag trail slope will be less there by energyconsumed to lift the body will be less when it is compared toclimbing straight up.

(c)How can a rocket change direction when it is far out inspace and is essentially in a vacum?
by changing the flow of fuel
