Review Cons When you skid to a stop on your bike, you can significantly heat the small patch of tire that rubs against the road surface. Suppose a person skids to a stop by hitting the brake on his back tire, which supports half the 90 kg combined mass of the bike and rider, leaving a skid mark that is 34 cm long, Assume a coefficient of kinetic friction of 0.80. Part...

As a 1.7x10 kg jet plane lands on an aircraft carrier, its tail hook snags a cable to slow it down. The cable is attached to a spring with spring constant 5.7x10* N/m Part A If the spring stretches 30 m to stop the plane, what was the plane's landing speed?

Review constants I Porodic Table The elastic energy stored in your tendons can contribute up to 35 % of your energy needs when running. Sports scientists have studied the change in length of the knee extensor tendon in sprinters and nonathletes. They find (on average) that the sprinters' tendons stretch 42 mm, while nonathletes' stretch only 33 mm Part A The spring constant for the tendon is the same for both groups,...

You can, in an emergency, start a manual transmission car by putting it in neutral, letting the car roll down a hill to pick up speed, then putting it in gear and quickly letting out the clutch Part A If the car needs to be moving at 3.3 m/s for this to work, how high a hill do you need? (You can ignore friction and drag.) Express your answer with the appropriate...
