Lab 7: Collisions, Momentum, and Impulse. PHYS 2305 Pre-lab Assignment Question Pre-1: What is net impulse and how is it related to momentum? Is impulse a vector or a scalar? Question Pre-2: How do you compute the impulse caused by a force from its force versus time graph? Question Pre-3a A truck traveling down the highway collides with a slower-moving mosquito flying in the same direction. Which of the following statements is true during the collision? (Circle the correct one.) The truck exerts a larger force on the mosquito than the mosquito exerts on the truck. The truck and mosquito exert the same size force on each other. The mosquito exerts a larger force on the truck than the truck exerts on the mosquito. Lab 7: Collisions, Momentum, and ImpulseQuestion Pre-3b: Explain your answer to Question Pre-3a. Which physics concepts or principles did you use? Question Pre-4a: A 2 kg object moving at a speed of 3.0 m/s collides with a 1 kg object at rest. The two objects have Velcro on them, so they stick together after the collision and continue as a combined unit moving in the same direction as the original moving object. With what speed does the combined object move after the collision? Question Pre-4b: Explain your answer to Question Pre-4a. Which physics principles or concepts did you use
