Barry · 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.
