The thing is, I'm not exactly sure how to apply it to this question:

*"A boy and a ball are at rest at the top of an incline. The ball rolls down the incline with an acceleration of 0.2m/s^2. Twelve seconds later the boy chases after the ball with an acceleration of 9.0m/s^2. The length the incline is 60m. Draw a diagram before solving the problem.*

*a. Will the boy catch the ball before the end of the incline? Hint "When are their displacements equal?"*

What am I supposed to solve for? Is it the velocities of the boy and the ball?
