Two identical motor ships pass under the same conditions the distance between
Two identical motor ships pass under the same conditions the distance between the two ports for different periods of time. Which motor ship develops the most power?
t1> t2.
S1 = S2.
The power N is the speed at which work A is done, how quickly this work is done. N = A / t, where A is the work performed, t is the time to complete the work.
Work is determined by the formula A = F * S, where F is the force that performs the work, S is the movement under the action of this force.
The movement S is determined by the formula S = V * t, where V is the speed of movement, t is the time of movement.
The power formula will take the form: N = F * V * t / t = F * V.
N1 = F * V1.
N2 = F * V2.
Since t1> t2 and S1 = S2, then V1 <V2.
N1 <N2.
Answer: the boat has more power, which has a shorter travel time between ports.
