Question

21. A ball released from rest on an inclined plane accelerates down the plane at 2 m/s2.Complete the table below showing the ball's velocities at the times indicated. Do not use a calculator for this; this is a reasoning question, not a calculation problem. Time (s)Velocity (m/s) 22. A bowling ball rolls along a level surface, then up a 30 slope, and finally exits onto another level surface at a much slower speed. a. Draw position-, velocity-, and acceleration-versus-time graphs for the ball. Exits slope Starts up slope

Answer 1

Time (s) velocity (m/s) 0 0 1 2 2 4 3 6 4 8 5 10 acceleration = 2 m/s^2 means velocity will increase 2 m/s per second. Position, velocity and Acceleration vs. time graphs.
