Answer: The work is negative

Explanation: The work is defined as the movement done by a force.

In this case, becuse the motocycle is driving upward in a inclinated ramp, the force of gravity will pull downwards, in the oposite direction of wich the motocycle is moving, this means that the work is negative, this means that the force is oposing to the motion of the motocycle and the motocycle needs to cancel this negative work in order to move.
