Problem 1: A car of mass 1000 kg moves at a constant speed of 20 m/s along a horizontal road where a frictional force is 200N. Calculate the power developed by the engine. If the car now moves up an incline at the same constant speed, calculate the new power developed by the engine. Assume that the frictional force is still 200 N and that sin(theta)=1/20 where theta is the angle of the incline to the horizontal. Problem 2: An...
