Lab 7 Post-Lab Questions Question Post-1: Find the impulse of the force shown on the force-time graph in Figure 7. B. (The force is acting along the x-direction) Show your calculations. Time lej Figure 7. 8 Question Post-2: Anobject of mass 2.5 kg is moving in the negative x direction at a speed of 3.0m/s. It experiences the force shown in Figure 7. 8. What is the final velocity of this object after it has experienced the impulse you found in Question Post-1?Question Post-3: An automobile of mass 1500 kg moving at 25.0 m/s collides with a truck of mass 4500 kg at rest. The bumpers of the two vehicles lock together during the crash. a) Compare the force exerted by the car on the truck with that exerted by the truck on the car during the collision. Is one force larger than the other, or are they equal in magnitude to each other? b) What is the final velocity of the car and truck just after the collision? Show your calculations
