1. The problem statement, all variables and given/known data A skateboarder, starting from rest, rolls down a 11.9-m ramp. When she arrives at the bottom of the ramp her speed is 6.77 m/s. (a) Determine the magnitude of her acceleration, assumed to be constant. (b) If the ramp is inclined at 29.8 ° with respect to the ground, what is the component of her acceleration that is parallel to the ground? 3. The attempt at a solution I dont even have a clue where to start??? How can i figure out the magnitude of acceleration without the time?? And i dnt even understand what the second part is asking at all? Any help on where to start is appreciated..
