What conclusions can be drawn about the final direction of movement in this collision? (assume the mass of each object is equal.
Object A will move to the left after the collision, however both objects will experience the same change in speed because forces in a collision are equal and they have the same mass.
Object A will move to the left after the collision, because more force is experienced to the left in this collision and they have the same mass.
What conclusions can be drawn about the final acceleration of movement in this collision?
Object A will have more acceleration after the collision because it applies less force in the collision
Object B will accelerate at a faster rate after the collision because A and B experience the same force, however B has less mass.
Object A and B will accelerate at the same rate because they experience the same force in the collision.
Which Trial, 1 or 2, did Car 2 experience a greater acceleration? Why?
Once you find the force of object A in trial 1 and trial 2 you can use F=MA to find the acceleration of each object B. I found that trial 1 has a greater acceleration because more force is applied per mass of object B.
Once you find the force of object A in trial 1 and trial 2 you can use F=MA to find the acceleration of each object B. I found that trial 2 has a greater acceleration because more force is applied per mass of object B.
There is not enough information to know why which crash has more acceleration.
