Newton's first law:

Force = Mass * Acceleration

Rearrange:

Acceleration = Mass/Force

And now to add numbers:

Acceleration = 2 Kg/40N

Cancels down to 1/20

Which gives: 0.05 m/s^2

How many newtons is 3000 pounds?

For an object experiencing a constant net force, Newton's Second Law of Motion can be used to obtain the equationF = ma,where F is the net force, m is the mass of the object and a is the acceleration of the object due to the net force, F. Rearranging the equation for acceleration and substituting in the mass of the box and the net force acting on it givesa = 900N/300kga = 3ms-2.


If an object has a mass of 20 kg what is the force of gravity acting on it on earth?

Force is equal to mass times acceleration, in this case the acceleration due to gravity. Gravity has an acceleration of 9.8 meters per second squared, so the total force is 196 Newton's. (1 Newton = 1 kg meter per second squared)


A force is exerted on a box and an equal and opposite force is exerted by the box what explains this?

A force is exerted on a box and an equal and opposite force is exerted by the box is an example that explains Newton's second law of motion. It states that for every action, there is an equal and opposite reaction.


What must happen in order for motion to occur?

I think there has to be a net force applied to the object in order for it to move. An example would be a box sitting on the ground. There is always gravity acting on the box, pushing it down, but there is also a force called the Normal force, applied by the ground on the box pointing up against gravity. These 2 forces, gravity and normal, cancel each other out perfectly, therefore the box does not move either up or down, it is stationary. Now if a person goes up to one side of the box, and pushes it horizontally, the box may begin to move if the force applied is greater than the friction between the box and the ground (i forget the name of the specific friction involved). As the box moves, there is also a constant friction between the box and the ground that pushes back against the direction of motion of the box. This friction would cause the box to stop moving once the person stops pushing, preventing the box from sliding on forever. ( i know some parts are vague in this, and im open to criticisms and corrections :P )


When the mover pushes the box up the ramp there is friction between the box and the ramp What is the efficiency of the ramp?

It depends on the mass of the box, the force exerted, the total displacement and the height the box was moved.

Predict the effect that significant friction would have on the acceleration of the box as it slides down the incline. Explain the cause of the predicted effect?

Significant friction would decrease the acceleration of the box as it slides down the incline. Friction opposes the motion of the box by creating a force that acts opposite to the direction of motion. This force would reduce the net force acting on the box, leading to a decrease in acceleration.


A box experiences a net force of 41N while it is being lifted.what is the acceleration of the box?

To find the acceleration of the box, you need to know its mass. Using Newton's second law (F=ma), where F is the net force of 41N and m is the mass of the box, you can solve for acceleration. Given only the force of 41N, the acceleration cannot be determined without the mass of the box.


Where a box of mass of kg is lowered vertically by a rope. find the force in the rope when the box is lowered with an acceleration of 4ms?

The force in the rope can be found using the equation F = m * (g + a), where m = mass of the box, g = acceleration due to gravity, and a = acceleration of the box. Plugging in the values, the force in the rope would be F = kg * (9.81 m/s^2 + 4 m/s^2) = N.


A worker with spikes on his shoes applies a constant horizontal force of 20 N to push a 40-kg box across a frictionless frozen lake. What is the acceleration of the box?

The acceleration of the box would be 0.5 m/s^2. This is calculated by dividing the applied force (20 N) by the mass of the box (40 kg).


If someone is sliding a box across the floor what does he need to know to calculate the force of the box?

To calculate the force of the box being slid across the floor, the person needs to know the mass of the box and the acceleration of the box. Using the equation F = ma (force equals mass times acceleration), the person can determine the force required to slide the box across the floor.


What is a force that lori should apply to a 5 kg box to give it an accelatration of 2ms?

To find the force, you would use Newton's Second Law: force = mass x acceleration. In this case, the force required to accelerate a 5 kg box with an acceleration of 2 m/s² would be 10 N (5 kg x 2 m/s² = 10 N).


A 5.5 kg box is pushed across the lunch table. The acceleration of the box is 4.2 ms2. What was the net force applied to the box?

The net force applied to the box is equal to the mass of the box multiplied by its acceleration, which is 5.5 kg * 4.2 m/s² = 23.1 N.


A force of 40 north is exerted on a 10-kg box. what is the box's acceleration?

The acceleration of the box can be calculated using the formula a = F/m, where a is the acceleration, F is the force applied, and m is the mass of the box. Plugging in the values, we get a = 40 N / 10 kg = 4 m/s^2. Thus, the box's acceleration is 4 m/s^2.


What force if you push a box?

When you push a box, you are exerting a force on it in the direction of the push. This force causes the box to accelerate if the force is greater than any opposing forces like friction. The magnitude of the acceleration depends on the mass of the box and the amount of force applied.


What would be easier to move a large empty box or a small heavy box?

an object's acceleration depends on the object's mass and the force applied to it. the lager the force applied to it.


How much force is needed to push a 10 kg box 5 meters?

To calculate the force needed, you'll need to know the acceleration due to gravity (9.8 m/s^2) and the distance the box is being pushed. The force required can be determined using the equation: force = mass x acceleration. In this case, the force required to push a 10 kg box 5 meters on a horizontal surface would be the force needed to overcome friction, which depends on the coefficient of friction and any other external forces acting on the box.


What force is needed to accelerate a box with a mass of 5 kg to an acceleration of 3 ms2?

The force needed can be calculated using Newton's second law, which states that force equals mass multiplied by acceleration. In this case, the force required would be 15 N (5 kg * 3 m/s^2).
