PLEASE HELP
a skier crosses a 100m flat section past the chair lift at a constant velocity of 6m/s, then accelerates downhill at a rate of 0.5m/s^2 until reaching a maximum velocity of 12m/s.
a) how long did it take them to speed up?
b) if the skier maintains the 12m/s speed for an additional 20s to the bottom of the hill, what is the total displacement of the skier after they got off the chairlift?
