PHYS 110 Lab #6

Wrap up question 1: Say the car in Collision B (1000 kg, 100 mph) takes 0.2 seconds to come to a stop rather than 0.1 s. Would you expect the damage to be the same as before, or would it be less? Justify your answer with a force comparison.

Wrap up question 2: Using your energy numbers from your measurements, explain why the impact of the 100 mph car is more than twice as bad in terms of damage as the 50 mph car. (Hint: Consider the total energy per collision, not just energy per car)

Wrap up question 3: Say car A and B are both traveling at 60 mph but car A takes twice the distance to come to a stop than car B does. What does that tell you about the magnitude of friction acting on each car? Explain using the connection of work and the change in kinetic energy.
