32. O A ball initially moves horizontally with velocity vy , as shown above. It is then struck by a stick. After leaving the stick, the ball moves vertically with a velocity vy, which is smaller in magnitude than v . Which of the following vectors best represents the direction of the average force that the stick exerts on the ball?\fUnit 4.2 Force-Momentum Homework 26. Normal Floor A 2 kg ball collides with the floor at an angle @ and rebounds at the same angle and speed as shown above. Which of the following vectors represents the impulse exerted on the ball by the floor? (A) (B) (C) (D) (E)Unit 4.2 Force-Momentum Homework 25. As shown above, two students sit at opposite ends of a bout that is initially at rest. The student in the front throws a heavy ball to the student in the back. What is the motion of the boat at the time immediately after the ball is thrown and, later, after the ball is caught? (Assume that air and water friction are negligible.)Unit 4.2 Force-Momentum Homework Immediately After the Throw After the Catch (A) Boat moves forward Boat moves forward Immediately After the Throw After the Catch (B) Boat moves forward Boat moves backward Immediately After the Throw After the Catch (C) Boat moves forward Boat does not move Immediately After the Throw After the Catch (D) Boat moves backward Boat does not move Immediately After the Throw After the Catch (E) Boat moves backward Boat moves forward15. F, An object is moving in a straight line along the 2-axis. The net force ", exerted on the object as a function of time t is shown in the graph. Which of the following could be the momentum p, of the object as a function of t ?\f2. Situation 1 - Hard Surface Situation 2 - Soft Surface m m V V 450 450 (0,0) -X 0,0) 30 V2 F A ball of mass m and velocity " contacts a hard surface at a 45" angle and bounces off the surface also at a 45" angle and at speed v, as shown in situation 1. Also shown is the force vector F representing the force exerted by the surface on the ball. Situation 2 shows the same ball moving with the same velocity and contacts a soft surface. The time of contact is greater with the soft surface than the hard surface. The ball bounces off the soft surface at an situation 2. angle of 30" and with speed v2
