How would i find the amount of work done on a inclined plane?

their is no angles or friction involved.

Force distance

If you know how much force was used and the distance of the inclined plane you take the force (F) and multiply it by the distance (D) to get work (W)

w = f * d

My answer is opptionc, just check with anyone else

The objects do not reach terminal velocity         there is not enough time from the time the object falls from when it hits the ground to achieve terminal velocity. an object must be placed higher to achieve terminal velocity in order to be in free fall.
