The force exerted on the box is 56 N
Explanation:
The work done by a force on an object is given by
![W=Fd cos \theta](https://tex.z-dn.net/?f=W%3DFd%20cos%20%5Ctheta)
where
F is the magnitude of the force
d is the displacement of the object
is the angle between the direction of the force and of the displacement
For the box in this problem, we have:
W = 2240 J is the work done
d = 40 m is the displacement of the box
Assuming that the force is parallel to the displacement, ![\theta=0](https://tex.z-dn.net/?f=%5Ctheta%3D0)
Solving the equation for F, we find the force exerted on the box:
![F=\frac{W}{d cos \theta}=\frac{2240}{(40)(cos 0)}=56 N](https://tex.z-dn.net/?f=F%3D%5Cfrac%7BW%7D%7Bd%20cos%20%5Ctheta%7D%3D%5Cfrac%7B2240%7D%7B%2840%29%28cos%200%29%7D%3D56%20N)

Answer:add resistance in the parallel circuit with the total resistance
Explanation:
the total resistance in the parallel circuit is also add resistance.
F=ma, in this case your force=-883 N and mass = 90 kg. F/m=a therefore acceleration=-883/90=-9.81 m/s/s
