Q1. The rate of energy use in a typical house is about 2 kW. If the kinetic energy of a car (mass 1456 kg) is equal to the total energy used by the house in 1 min, what is the car's speed?

Q2. A flywheel in a motor is spinning at 560 when a power failure suddenly occurs. The flywheel has mass 40.0 and diameter 75.0. The power is off for 34.0, and during this time the flywheel slows down uniformly due to friction in its axle bearings. During the time power is off, the flywheel makes 240 complete revolutions.
