As part of an obstacle course, an athlete must kick a soccer ball into al meter wide and 10 meter deep pit such that the ball hits a target at the bottom of the pit. In practice, a dynamics student that is participating in the race kicks the soccer ball such that the soccer ball will bounce off the far wall of the pit 5 meters below the surface and head towards the target. If the velocity of the ball before striking the wall at point at point A is vA=3.21- 10j , determine the t-component of the ball velocity vector (in m) after striking the wall. The size of the ball and the target are negligible relative to the dimensions of the pit, the gravity acceleration must be considered as g = 10 and the coefficient of restitution at point A is e =0.55. 5 m 10m Im 目
