Question
1) Two objects labeled A and B collide. Consider the magnitude of the force that object A exerts on B during the collision and compare it to the force B exerts on A. Scenario: A and B are identical objects, and B is at rest before the collision. Would the two forces be the same, or if not which is greater? Explain your reasoning.2) Given a graph of acceleration vs time, how do you determine how the velocity changes as a function of time 1) Two objects labeled A and B collide.

2) Given a graph of acceleration vs time, how do you determine how the velocity changes as a function of time
Explanation / Answer
1. Forces acting during collision will be equal and opposite to each other as according to Newton’s Third Law of Motion, ‘’To every action there is equal and opposite reaction’’. When A exerts force F on B then B exerts force –F on A.
2. Acceleration = Rate of change of velocity
Acceleration = Change in velocity/ Time
Or Change in velocity = Acceleration* Time
We can change in velocity as a function of time by finding area under acceleration time graph. We can find it by integrating acceleration as a function of time or by simply calculating area under acceleration time graph for a given time interval
