Question
An elevator with total mass of 1,600 kg is moving up ward with constant acceleration. A friction in the system resists the motion with force of 4,000 N constantly. Find how much power is required to lift the elevator at a constant acceleration of 1.0 m/s2 at the instant the speed of the elevator is v = 3 m/s?

- When an automobile moves with constant speed down a highway, most of the power developed by the engine is used to compensate for the mechanical energy loss due to frictional forces exerted on the car by the air and the road. If the power developed by the engine is 195 hp, estimate the total friction force acting on the car when it is moving at a speed of 30 m/s. One horsepower equals 746 W.arrow_forwardUse g = 9.8 m/s². A force of constant magnitude pushes a box up a vertical surface, as shown in the figure. The box moves at a constant speed. If the mass of the box is 5.5 kg, it is pushed 3.8 m vertically upward, the coefficient of friction is 0.35, and the angle 0 is 30.0°, determine the following.
