Work done = Force x distance moved in the direction of force
So work done = 15 x 20 = 300 joule
That force 15 newton would be the necessary and equivalent force to overcome the static frictional force. Static frictional force depends, of course, on the mass of the box.
Just multiply the force times the distance, to get the work. The number of students is irrelevant - it seems that 800 Newtons is the total force.

A force of 20 newtons acting through a distance of 40 meters produces
work equal to (20 x 40) = 800 newton-meters = 800 joules.
The weight of the cart doesn't matter.

It takes 160J/8m = 20N Newtons force to do the job.
Work = force x distance = (4 x 10) = 40 newton-meters = 40 joules
your weight
A force of 4500 Newtons is required.
F = M A = 2 x 6 = 12 newtons

approximately 7000 newtons
Force = Mass * Acceleration = 1 * 2 = 2 Newtons
There is some confusion here. 500 newtons IS a force. You don't "give a force an acceleration". You can accelerate an object (which has a mass), but not a force.
F = m a = (976) (2.5) = 2,440 newtons

Power = (energy) / (time) =(200 newtons x 4 meters) / (4 seconds) =200 newton-meters per second = 200 watts

A force of 4500 Newtons is required.
F = (m) x (A) = (1) x (12) = 12 newtons
F = M A = 2 x 6 = 12 newtons
