When a ball is rolled uphill and released, it gradually slows dawn,

When a ball is rolled uphill and released, it gradually slows dawn, momentarily stops at its highest point in the upward journey, and then rolls downhill. In the sketch you see v; and vf as the velocities of the ball right before reaching to the highest point and right after it has turned around, respectively. You should be able to find the direction of change in velocity vector at the turning point by using these two vectors. Draw the change in velocity vector. What direction did you find for the change in velocity vector? B A C 4 Vf
