- 1. A ball having 500.0 g hits wall with velocity 10.0 m/s. Wall applies to the ball and it turns back with velocity 8.0 m/s. Find the 5000.0 N for time of ball-wall contact. 2. A projectile is launched at 40° to the horizonal with initial speed 15 m/s. Determine the maximum height reached. (assume g = 9.81 m/s²)A. If you catch the ball, with what speed do you and the ball move afterwards? B. If the ball hits you and bounces off your chest so that afterward it is moving horizontally at 8.25 m/s in the opposite direction, what is your speed after the collision?10. A poolio-coolio claims that he has perfected the greatest trick shot of all time. He claims that he can arrange three pool balls in the center of the table such that when he hits them with the cue ball some extraspecialness happens. He claims that the cue ball comes to rest, two of the balls move directly away from each other along a line perpendicular to the direction of the incoming cue ballI, and the remaining ball moves in the direction of the cue balls original path. All of the balls involved have the same mass. Using your cunning physics prowess, prove that he is full of hot air. Hint: You will need to use momentum and kinetic energy.

- A 150g baseball is thrown directly upwards with a velocity of 20.0m/s. 1.00 second later an 8.00g bullet is fired upwards at the baseball with a velocity of 300m/s. The bullet collides and embeds itself in the ball. Find the maximum height of the bullet/ball pair.A 1500kg sport car is moving westbound at 20m/s on a level road when it collided with a 4000kg truck driving east on the same road at 15m/s. The two vehicles remain locked together after the collision. a)what are is the magnitude of the velocity of the two vehicles just after the collision?Construct Your Own Problem Consider a ball tossed over a fence. Construct a problem in which you calculate the ball's needed initial velocity to just clear the fence. Among the things to determine are; the height of the fence, the distance to the fence from the point of release of the ball, and the height at which the ball is released. You should also consider whether it is possible to choose the initial speed for the ball and just calculate the angle at which it is thrown. Also examine the possibility of multiple solutions given the distances and heights you have chosen.
