You exert a force of 75 newtons on a rock. You push and you push, but you can’t budge it. You are exhausted! How much work did you perform?
Acadia Jenks
Unfortunately, 0. The rock has 0 displacement, so despite force being exerted no work was done (at least in physics terms).

If earth pulls on a puppy with a force of 2 newtons what amount of force does the puppy exert on earth?
Two newtons is the puppy is just standing there. If the force were more, the puppy would be jumping into the air.
A book weighing 29 N is placed on a table How much support force does a table exert on the book?
29 Newtons
Can 100kg weight falling produce 2000 newtons of force?
Yes, but only if acceleration is increased to 20m/s^2. Without that increase a 100kg mass would exert a force of about 980.7 newtons.
How much force ( in newtons ) does a baseball pitcher have to exert on a 250g baseball to make it accelerate to 50 ms the instant that leaves his hand?
?
How many newtons of force does a 50.0 kg deer exert on the ground because of gravity?
50 pounds-force = 222.26 newtons (rounded)
How many newtons of force will you exert to lift 170gram weight?
A minimum of 1.667 newtons.
If a bat exerts 40 newtons on the ball how many newtons does the ball exert on the bat?
zero
How many Newtons would a football weigh if it had a mass of 400 gHow many Newtons?
Something with a mass of 400g would exert a force of 3.9228 newtons.
If earth pulls on a puppy with a force of 2 newtons what amount of force does the puppy exert on earth?
Two newtons is the puppy is just standing there. If the force were more, the puppy would be jumping into the air.

How many newtons of force does a rocket need to take off?
This depends on the weight of the rocket, weight being the mass of the rocket multiplied by earth's gravitational pull. To take off, the rocket needs to exert force larger than the weight, and for a sufficient amount of time to break out of orbit. For instance, if the rocket had a mass of 1kg, it'd exert (1 * 9.8), or 9.8 Newtons of force towards to ground via it's weight (9.8 being the acceleration towards the ground due to gravity). This means that to start to accelerate away from the ground, the rocket would need to exert force higher than 9.8 Newtons. If your hypothetical rocket has a mass of x kg, then it will need to exert a force greater than 9.8x newtons, ignoring air resistance and decaying of the gravitational field.
How much force neutons does a 110.0 kg mass exert on the floor?
If the floor is on Earth, then the weight of 110.0 kg of mass is 1078.8 newtons. (rounded)
What happens when you exert force on an abject and it exerts force on you?
According to Newtons 3rd law, "Every action has an equal and opposite reaction". if you exert force on an object, the object will exert an equal and opposite force on you. when the forces exerted by you and the object balance a state of equilibrium is attained. however if you exert a force greater than the weight of the body, the body begins to move and work is done.
