A skateboarder, starting from rest, rolls down a 15.0 m ramp. When she arrives at the bottom of the ramp her speed is 7.95 m/s.

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

(b) If the ramp is inclined at 23.0° with respect to the ground, what is the component of her acceleration that is parallel to the ground?

2. Relevant equations

v squared=v initial squared +2ax

kinematics equations..

3. The attempt at a solution

I tried so many times to get the answer! I tried making a right triangle with 23 degree angle and cos 23=x/2.1, it didnt work out...i'm so confused, please help!
