Question

A skier begins skiing straight down a hill having a constant slope, starting from rest. If friction is negligible, as the skier goes down the hill, his or her                                          

      acceleration is zero.
                                        acceleration increases with time.
                                        acceleration is constant, with a value of roughly 10 m/s/s.
                                        acceleration is constant, with a value less than 10 m/s/s

Explanation / Answer

acceleration is constant, with a value less than 10 m/s/

The speed of the skateboard increases as it rolls down.
Just like your speed would increase while falling down.

However, when you fall down, you fall down with a constant acceleration of g = 9.8 m/s2.
Since you're on a slope now with your skateboard, would your acceleration be less than when you fall down?
