Abike can climb the inclined road at uniform speed of 72 km/hr by applying force 500n what will be the power applied by the bike ?

10 kW

Explanation:

First convert km/hr to m/s.

72 km/hr × (1000 m / km) × (1 hr / 3600 s) = 20 m/s

The power is:

P = Fv

P = (500 N) (20 m/s)

P = 10000 W

P = 10 kW

The power applied by the bike is 10 kW.

double the distance = divide strength by 4
