You carry a box of weight 3 lbs (1 lb = 4.45 N ) up a horizontal ramp at a constant velocity. The ramp has a height of 7.0 m. The base of the ramp is 22.5 m. There is a drag force (FD) caused by a gust of wind down the ramp that pushes down and parallel to the surface of the ramp with a constant force of 3.5 N. What is the net work done of the box?

131 J

2948 J

917 J

0 J

The same net force is applied to object A and object B over the same distance. Object A has a mass of 10 kg. Object B has a mass that is 20 kg. If object A has a change in kinetic energy of 3.0 J then

object B also has a change in kinetic energy of 3.0 J

object B has a change in kinetic energy less than 3.0 J because its mass is less.

object B has a change in kinetic energy greater than 3.0 J because its mass is more

not enough information
