So... No sey amigos, no comprende. Okay so I need some help on this homework question for my physical science class. If a ramp is at an angle of 9.2 degrees, how long will it take a marble to accelerate to a speed of 10 m/s (from an intial speed of 0 m/s)? The paper says use the acceleration formula and solve for time but I still don't understand... Thanks so much guy 100th post <3

Well the problem is that you dont have a starting velocity or a means for acceleration...unless the ramp is sloping down...is it sloping down?
