The tire takes about 3 seconds to roll down the inclined section of the track. The incline is at 7.5° from horizontal. The tire rolls along the flat part for about 2 seconds.
1.Estimate the kinetic energy of the tire (mass is approximately 25 lbs) when it reaches the bottom of the inclined portion of the ramp.
2.The flat portion of the tire’s track is 3.5 m long. It takes the tire about 2s to roll across it. Is this what you would have expected from your answer to #1? Explain your answer.
3.After the tire hits the hammer, it moves 0.27 m, still in the “forward” direction, in 7 video frames (each ~1/30 s). What is the tire’s change in momentum?
4.Assuming that the force of the impact was constant, and that the impact occurred over 1/30th of a second, what is the force applied to the hammer?
