This is very good conceptual question and can clear your doubts regarding work-energy theorem.
Whenever force is perpendicular to the direction of the motion, work done by that force is zero.
According to work-energy theorem,
Work done by all the force = change in kinetic energy.
here, work done = 0.
Therefore,
0=change in kinetic energy
This means kinetic energy remains constant.
Hope this helps
We know that:
Solving for Distance:
- Distance = Work / Force
- Distance = 1220 J / 280 N
<h3> Distance = 4.36 m </h3>
