Question

A dog uses 300 N of force to run 50 m with a speed of 5.9 m/s. How much power does he expand

Answer 1

1.47kW

Step-by-step explanation:

F = 300N, s = 50m, v = 5.9m/s

P = W/t

= (F× )/t

= F × v

= 300 × 5.9

= 1470Watt

= 1.47kW

Answer 2

Answer:1770 watts

Step-by-step explanation:

Power=force×velocity

Power=300×5.9

Power=1770watts
