Also 100 newtons. Actually, that would only hold it in place - to push it back, you would need slightly more than 100 newtons.
The force needed to hold up a 20kg bag of sand would be equivalent to the weight of the bag, which is approximately 196 Newtons (N) on Earth.
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.
The force needed can be calculated using Newton's second law, F = m * a, where F is the force, m is the mass of the car (1000 kg), and a is the acceleration (3 m/s^2). Therefore, the force needed would be 3000 Newtons.
The force needed to accelerate an object is given by the formula: force = mass x acceleration. For the bowling bowl with a mass of 25kg and acceleration of 2m/s^2, the force required would be 50 Newtons.
To move 1 ton (2000 pounds) on a surface with no friction, you would need a force equivalent to its weight, which is about 2000 pounds-force. This force is equivalent to about 8,900 newtons.

The force needed to hold up a 20kg bag of sand would be equivalent to the weight of the bag, which is approximately 196 Newtons (N) on Earth.
Newtons are the force one object exerts on another. The weight you see on a bathroom scale is how much the scale pushes back, which equals the Newtonian force. However, mass and Newtons are different but related. Newtons is the gravitational pull multiplied by the mass. The basic equation is: (mass in grams)(9.8)=Force in Newtons 9.8 is the gravitational pull on every object on Earth.
Force = Mass * Acceleration = 1 * 2 = 2 Newtons
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 A = (13) x (25) = 325 newtons

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.
