If the proper units are used (Watts, m/s and newtons, for example),
Power = Force * Velocity
First convert to SI units:
88 km/h = 24.44 m/s
18 Hp = 13,428 Watts
Force = P/V = 549 newtons
Power = Force * Velocity
First convert to SI units:
88 km/h = 24.44 m/s
18 Hp = 13,428 Watts
Force = P/V = 549 newtons

13,428/24.4= 5.5x10^2N
