A skateboarder, starting from rest, rolls down a 13.9-m ramp. When she arrives at the bottom of the ramp her speed is 6.06 m/s. (a) Determine the magnitude of her acceleration, assumed to be constant. (b) If the ramp is inclined at 33.2 ° with respect to the ground, what is the component of her acceleration that is parallel to the ground?
