A 200 kg wagon climbs up a hill of slope 30-degrees in 1 minute at a speed of 10 m/s. How much power is delivered by the engine? (Assume g = 10m/s2)

40 kW 20 kW 26 kW 10 kW

20 kW

Weight of car = m x g     = 200 x 10 = 2000 N Total force (F) = 2000 N Velocity (v) = 10 m/s P = F x v     = 2000 x 10 = 20000 W      = 20 kW.
