A 61.0 kg sled is pulled from rest by a snowmobile and accelerates at 2.4 [forward] for 5.5 s. The force of friction acting on the sled is 111.0 N [backwards]. The total mass of the snowmobile and the driver is 461.0 kg and the force of friction acting on the snowmobile is 546.0 N [backwards]. Determine the power developed by the snowmobile engine.
