A skateboarder, starting from rest, rolls down a 12.5 m ramp. When she arrives at the bottom of the ramp her speed is 6.10 m/s.
(a) Determine the magnitude of her acceleration, assumed to be constant. . m/s2
(b) If the ramp is inclined at 26.5° with respect to the ground, what is the component of her acceleration that is parallel to the ground? . m/s2
