A2kg box is pushed along a flat frictionless surface with an applied force of 53.91newton j+19.62 j were j is horizontal and j is vertical if the box moves 10m horizontal in 90 seconds what is the work and power that is required to complete the movement

Since the box doesn't move vertically at all, no work is done by the vertical component of the force.

If 53.91 Newtons is the horizontal component of the force (very unclear in the question), then the work done is

Work = (force) x (distance)

Work = (53.91 N) x (10 m)

Work = 539.1 Joules

Power = (work done) / (time to do the work)

Power = (539.1 joules) / (90 sec)

Power = (539.1/90) (joule/sec)

Power = 5.99 watts

Note:  If the mass of the box is only 2 kg, and you push it along the surface with a constant force of 53⁺ Newtons, and the surface really is frictionless, then that box is gonna cover a WHLE LOT more than 10 meters in 90 seconds.  I get 109,168 meters !

the force on the thing and the distance the force moves the thing
