A joule is a neuton metre. i.e. 10*5 = 50 joules are required.
Work is force x distance = 700 x 4 = 2800 Joules
A force of 20 newtons acting through a distance of 40 meters produceswork equal to (20 x 40) = 800 newton-meters = 800 joules.The weight of the cart doesn't matter.
The idea here is to multiply the force by the distance.
Increase in the object's potential energy = (force) x (distance) = (200) x (4) = 800 newton-meters = 800 joulesPower = (800 joules) / (4 seconds) = 200 joules per second = 200 watts
joules is energy, not a force

334.8 Joules
One foot-pound of force equates to about 1.355818 joules.
The needed heat is 47,65 Joules.
Exactly 2.6 joules for each meter that you keep pushing it.If the book doesn't move, then there's no work.
Depends on how much force is placed into a punch.
