The ball exerts an equal and opposite force of 8 newtons on the bat, according to Newton's third law of motion. So, the force exerted by the ball on the bat is also 8 newtons.
To push a force of 100 Newtons back, you would need to exert an equal force of 100 Newtons in the opposite direction. This is in accordance with Newton's Third Law of motion, which states that for every action there is an equal and opposite reaction.
While the ball does exert a force on Earth according to Newton's third law of motion, the force exerted by the ball on Earth is much smaller compared to the force exerted by Earth on the ball due to Earth's much larger mass. This makes the effect of the ball's force on Earth negligible in comparison.
Using a single fixed pulley will not change the amount of effort needed to lift a load. You will need to exert a force equal to the weight of the load, in this case 10 newtons, to lift it. The fixed pulley only changes the direction of the force needed, not the amount of force required.
7500 Newtons is the equivalent of approximately 1690 pounds-force. It is a metric unit of force, commonly used in the SI system of units.
The table exerts a support force on the book equal in magnitude to the weight of the book in the opposite direction, which is 29 N. This support force counteracts the gravitational force acting on the book, keeping it in equilibrium on the table.
If the floor is on Earth, then the weight of 110.0 kg of mass is 1078.8 newtons. (rounded)
No matter how much force you exert downward, it shall avail you naught. No downward force acting directly on the object can ever succeed in lifting it.
To push a force of 100 Newtons back, you would need to exert an equal force of 100 Newtons in the opposite direction. This is in accordance with Newton's Third Law of motion, which states that for every action there is an equal and opposite reaction.
Work = Force X Distance 20 N X 10 m = 200 N-m
While the ball does exert a force on Earth according to Newton's third law of motion, the force exerted by the ball on Earth is much smaller compared to the force exerted by Earth on the ball due to Earth's much larger mass. This makes the effect of the ball's force on Earth negligible in comparison.

A tennis ball is 0.125 pounds. A forceof0.125 Ibs converts to 0.556 newtons.
Force = mass x acceleration Force = Akg x 2m/s^2 Unit for force here is in Newtons (N)
Using a single fixed pulley will not change the amount of effort needed to lift a load. You will need to exert a force equal to the weight of the load, in this case 10 newtons, to lift it. The fixed pulley only changes the direction of the force needed, not the amount of force required.
F = (M) x (a) = (25) x (2) = 50 newtons.
Work done = force multiply by displacement so W = 20X 10 = 200 Nm now 1Nm = 1 joule then the answer is 200 J
