Please show steps on the second Prelab and explanations on the first ! Thanks in advance!
Pre-lab question: A bug and a truck collide. Answer the following . Which object, the bug or the truck, . Which object has the greatest " Which object has the greatest change has the larger force exerted on it? Oh impulse delivered to it? in momentum? Which object has the greatest acceleration? If we now consider two colliding objects as a system, then the action-reaction forces are internal and of no consequence. (Can you push your car down the road by sitting in the seat and pushing on the dashboard?) In this case, then the total momentum of the system does not change as a result of the collision. So with two objects that collide: -(P, +P2)AnerColsion ms is a statement of Conservation of momentum Pre-lab question: A 10,000kg train car traveling east at 10m/s collides and couples t stationary 15,000kg train car. How fast do the pair of cars travel after the collision?Explanation / Answer
Both have equal and opposite force exerted on them. Impulse(which is also equal to change in momentum) is product of force and time of collision, which is same for both; so impulse is same. Change in momentum is same for both. Acceleration is ratio of force and mass. force remaining same, bug with lesser mass has greater acceleration.
Initial momentum = final momentum
So, 10000*10 = (10000+15000)*v
So, v = 100000/ 25000 = 4 m/s with the direction same as before.
