A student wearing frictionless in-line skates on a horizontal surface is pushed by a friend with a constant force of 50.0 N.
How far must the student be pushed, starting from rest, so that her final kinetic energy is 350 J?
Pleaseeeee

Answer:

Distance = 7 meters.

Explanation:

Given the following data;

Force = 50N

Kinetic energy = 350J

To find the distance;

We know that energy possessed by an object over a distance represents the work done by the object.

Mathematically, work done is given by the formula;

Workdone = force * distance

350 = 50 * distance

Distance = 350/50

Distance = 7 meters.
