A student on a skateboard is moving at a speed of 1.40 m/s at the start of a 2.45 m high and 12.4 m long incline. The total mass is 45.0 kg, air resistance and rolling resistance can be modeled as a constant friction force of 41.0 N, and the speed at the lower end of the incline is 6.60 m/s. Determine the work done (in J) by the student as the skateboard travels down the incline. J
