For friction; one cable passing around a large pulley connects the cars, the second is pulled by a small motor. Suppose the mass of each car (with passengers) is 1300 kg, the coefficient of rolling friction is 0.030, and the cars move at constant speed. the coefficient of rolling friction is 3.0×10−2, and the cars move at constant speed.
a) What is the tension in the connecting cable?
b) What is the tension in the cable to the motor?
