My thinking: Convert 52 kW to 5200 W. Force of friction = force applied because there is not a net force. Work = force x distance.

**drwls**, Thursday, November 15, 2007 at 2:21amSince Work = Force x Distance,

Power = Force x Velocity

Average force = Power/Velocity

= (52,000 kg m^2/s^3)/(21 m/s) = 2476 N
