 problem 1

Compute the kinetic energy, in Joules, of a 1,600-kg automobile traveling at 50 kph.

problem 2

A 1,000-kg elevator carries a maximum load of 800-kg. The constant frictional force of 4,000 N retards its motion upward. What minimum power, in kilowatts, must the motor deliver to lift the fully loaded elevator at constant speed of 3.0 m/s?
