Engineers are designing a system by which a falling mass m imparts kinetic energy to a rotating uniform drum to which it is attached by thin, very light wire wrapped around the rim of the drum (the figure (Figure 1) ). There is no appreciable friction in the axle of the drum, and everything starts from rest. This system is being tested on earth, but it is to be used on Mars, where the acceleration due to gravity is 3.71...

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...
