A ball, released from rest, rolls down ramp A, then along the floor, then up ramp B. Rounded segments at the bottoms of the ramps allow the ball to roll smoothly from a ramp to a floor and vice versa. Air resistance is negligible.
Sketch the balls velocity vs time and acceleration vs time graphs (a detailed description is ok if you can't upload an image) from the moment its released until the moment it reaches its peak on the second ramp. Must know when the balls on ramp a, the floor and ramp b.
