Question: In 1964, after the 1250-kg jet-powered car Spirit of America lost its parachute and went out of control during a run at Bonneville Salt Flats, Utah, it left skid marks about 8 km long. (This earned a place in the Guinness Book of World Records for longest skid marks).
Part A: If the car was moving initially at a speed of 843 km/h, and was still going at 250 km/h when it crashed into a brine pond at the end of the skid marks, find the coefficient of kinetic friction?
Part B: What was the kinetic energy of the car 39 s after the skid began?
I need help to find the coefficient of kinetic friction.
A circuit consists of an 100- resistor in series with a 5.5-?F capacitor, the two being connected between the terminals of an ac generator. The voltage of the generator is fixed.
