Chapter 6, Problem 65P

(choose chapter or problem)

Look Out!? A snow-ball rolls off a barn roof that slopes downward at an angle of 40o (?Fig. P3.59?). The edge of the roof is 14.0 m above the ground, and the snowball has a speed of 7.00 m/s as it rolls off the roof. Ignore air resistance. (a) How far from the edge of the barn does the snowball strike the ground if it doesn’t strike anything else while falling? (b) Draw x-t, y-t, vx-t, and vy-t graphs for the motion in part (a). (c) A man 1.9 m tall is standing 4.0 m from the edge of the barn. Will the snowball hit him?
