Aforce
f acts in the x - direction, its magnitude given by f = ax^2, where x is in meters and a =5.0n/m^2
. find the work done by this force as it acts on a particle moving from x = 0 to x = 6.0 m.

the moving of the box is a result of centripetal force. think of that  as a car or a truck in this case creates a turn, the force of friction performing upon the turned wheels of the car runs centripetal force obligatory for circular motion for the things inside it.
