A 70.0 kg sled is pulled from rest by a snowmobile and accelerates at 2.2 m/s² [forward] for 7.5 s. The force of friction acting on the sled is 125.0 N [backwards]. The total mass of the snowmobile and the driver is 455.0 kg and the force of friction acting on the snowmobile is 549.0 N [backwards]. Determine the work done by the snowmobile engine. Input your answer with 1 decimal place
