A skateboarder starting from rest rolls down a 130 m ramp

A skateboarder, starting from rest, rolls down a 13.0 m ramp. When she arrives at the bottom of the ramp her speed is 6.00 m/s.

(a) Determine the magnitude of her acceleration, assumed to be constant.

(b) If the ramp is inclined at 23.5° with respect to the ground, what is the component of her acceleration that is parallel to the ground?
