The answer is 1,600 J.
A work (W) can be expressed as a product of a force (F) and a distance (d):
W = F · d
We have:
W = ?
F = 20 N = 20 kg*m/s²
d = 80 m
_____
W = 20 kg*m/s² * 80 m
W = 20 * 80 kg*m/s² * m
W = 1600 kg*m²/s²
W = 1600 J

A 2.3kg box, starting from rest, is pushed up a ramp by a 10 N force parallel to the ramp. The ramp is 2.0 m long and tilted at 17 degrees. The speed of the box at the top of the ramp is 0.80m/s.How much
