1. The problem statement, all variables and given/known data A puck is let go on the top of a frictionless slope. The slope is length .74 m and 3.5 degrees above the horizontal. What is the acceleration and how long does it take the puck to go down the slope? 2. Relevant equations Fnet=ma Fg=mg? 3. The attempt at a solution If I was given m, I could just draw a free body diagram and find Fnet down the slope and then use m to find acceleration using Fnet=ma Without mass, I am quite lost? Can it be done?
