1. (a) A particle travels horizontally between two parallel walls separated by 18.4 m. It moves toward the opposing wall at a constant rate of 9.4 m/s. Also, it has an acceleration in the direction parallel to the walls of 3.6 m/s^2, what will be it's speed when it touches the wall? (b)At what angle with the wall will the particle strike? 2. Relevant equations v^2= vi^2 +2a(x-xi) 3. The attempt at a solution\ (a) the thing is like this, the body diagram shows that the particle takes a curve that is similar to a parabola, and that messes my mind. I think they are asking just for the final velocity. correct me if I'm wrong, please.
