Question

An elevator weighing 15,000 newtons is raised one story in 50 seconds. if the distance between stories is 3.0 meters, how much power is required of the motor?

Answer 1

Power is force multiplied by the velocity, expressed as P = F* d/t where d is distance and t is time. d/t is termed also as velocity. Substituting the given date where F is equal to 15000 newtons, distance is equal to 3 meters and t is equal to 50 seconds, power is equal to 900 Joules per second or 900 watts.

Answer 2

Answer:

900 w
