- In a time of T seconds, a motorcycle can accelerate from rest to the speed v. (a) Determine the amount of time (in terms of 7) required for it to accelerate from v to 6v if the power output remains constant. At = (b) Determine the speed of the motorcycle (in terms of v) 3T after starting. Vf=An elevator is designed so that when it travels upward, it has constant acceleration from rest to its cruising speed of 2.0 m/s in a time of 4.0 seconds. The elevator has a mass of 625kg. Assume friction is ignored. A. Determine the average power (in W) of the elevator motor while its accelerating upward to its cruising speed. B. Determine the motor power (in W) when the elevator is moving upward at its cruising speed.What average mechanical power (in W) must a 70.5 kg mountain climber generate to climb to the summit of a hill of height 305 m in 47.0 min? Note: Due to inefficiencies in converting ch energy to mechanical energy, the amount calculated here is only a fraction of the power that must be produced by the climber's body. HINT W Need Help?

- A car engine produces a constant power of P = 341 hp. The car and motor have a combined mass of m = 1830 kg. 1.) The car starts from rest, after t=5 seconds, what is the cars speed, you may assume no energy is required to spin the tires. 2.) Assume a dragster of mass m=1000kg can accelerate to cover 450 m and accelerate in 7.2 s from a dead stop, how much horsepower is the engine producing, assuming acceleration is constant?A car accelerated from rest to a speed of 20 m/s in a time of 5.6 s. The car has a weight of 9000N. Determine the average power needed to accelerate the car.While driving, you notice that your 1150 kg car slows down from 70 mph to 45 mph in about 4.85 s when it is in neutral. How much horsepower is needed to keep the car moving at a constant velocity?
