The two forces of interest are the car's weight (W = 9000) acting vertically down and the pushing force, P, acting parallel to, and up, the hill. If the car drops a vertical distance h and an inclined distance s then the works are; Work done by gravity = Wh (positive because they are both in same direction) and Work done by pusher = -Ps (negative because they are opposite). Now I don't know what your 5 meters is, h or s. Assuming negligible friction, the net work done by all forces, Wh - Ps = change in objects kinetic energy. If the change in kinetic energy is negligible or zero then you get , Ps = Wh. Now if h=5 meters then you can calculate Wh = 9000x5 = 45000 joules., and then Ps = 45000 joules. If s is the 5 meters and not h ,then I don't know how you can calculate a number without more information. So if all the assumptions are right; negligible friction, h = 5 , and negligible KE change then; (1) work done by gravity = 45000 j ; work done by pusher = - 45000 j ; net work done = 0

How many newtons of gravitational force are exerted on one kilograms of mass?
9.81 N
If 300-n action force is exerted to the right the reaction force will be?
300 Newtons to the left. Remember, there is an equal and opposite force. So the force is equal, 300 Newtons, and it is opposite (opposite of right is left).
What is the force in newtons exerted on a surface measuring 0.25 m2 if the pressure is 101 Pa?
Pressure = Force per unit area = Force/area Therefore the force is equal to the pressure*the area. Force = pressure*area = 101*0.25 = 25.25 Newtons
What equals force exerted on a surface divided by the total area over which the force is exerted?
That is called pressure. For example, the SI unit for pressure is the Pascal, which is equal to newtons / square meters.
A rock has a weight of 50 N The force that the earth exerts on the rock is?
"Weight" is the force exerted by gravity. Thus, 50 Newtons.
What is the force exerted by gravity in measured in?
Newtons
What word means force exerted against something?
newtons
What science word means force exerted against something?
newtons
What equals the force exerted on a surface divided by the total area over which the forces are exerted?
Newtons/square meters.
How much Newtons of force does the sun have?
The force exerted by the sun on any object depends on the mass of that object so there is no simple answer. The sun's force of a planet like Jupiter will be several orders of magnitude greater than the force exerted on an electron, for example.

Newtons third law examples?
You punch a wall but your hand stops. The wall has exerted a force that is equal and opposite to the force you applied to it.
How much Pascals is exerted on a board that measures 4 meters by 6 meters with a hammer using 35 Newtons of force?
1.46 Pascals is exerted on the board.
