The net force acting on the car can be calculated using Newton's second law: Fnet = ma. Given the acceleration of 3 m/s^2 and mass of 1200 kg, the net force is 1200 kg * 3 m/s^2 = 3600 N. Therefore, the resistance to motion can be calculated by subtracting the force due to the engine from the net force: 3600 N - 5000 N = -1400 N. The magnitude of the resistance to motion is 1400 N.

Can you increase the horizontal component of the force that you exert on the mower without increasing the magnitude of the force?
No, the horizontal component of a force is directly related to the magnitude of the force. Increasing the horizontal component of the force would require increasing the magnitude of the force itself.
Will a vector at 45 degrees to he horizontal be larger or smaller than its horizontal and vertical components?
The magnitude of the vector at 45 degrees to the horizontal will be equal to the magnitude of its horizontal and vertical components. This is because the components are obtained by using trigonometric functions of the angle, and in this case, at 45 degrees, those functions yield the same value for both the horizontal and vertical components as the magnitude of the vector.
A box rest on a frozen pond which serves as a frictionless horizontal surface .if a fisherman applies a horizontal force with magnitude 48.0N to the box and produces an acceleration of magnitude 3.00m?
The mass of the box is 16 kg (48.0N / 3.00 m/s^2).
Is resistance a vector?
A vector quantity is one that has a magnitude (a number), and a direction. No, resistance is not a vector quantity; it is a scalar quantity (only magnitude).
What the meaning of accelaration?
Acceleration is the rate of change of velocity of an object over time. It can be an increase or decrease in speed, or a change in direction. It is a vector quantity, meaning it has both magnitude and direction.

No, the horizontal component of a force is directly related to the magnitude of the force. Increasing the horizontal component of the force would require increasing the magnitude of the force itself.
What is the horizontal component of a vector whose magnitude is 70 and whose direction relative to the horizontal is 20?
A vector with magnitude = 70 , directed 20° above or below horizontal,has a horizontal component of70 cos(20°) = 65.778 (rounded)
How do you find the magnitude of the horizontal components of forces?
Find an expression for the magnitude of the horizontal force in the figure for which does not slip either up or down along the wedge. All surfaces are frictionless.
A 100kg man is hanging 5m above the horizontal ground.What magnitude of weight of the man?
The magnitude of the weight of the man is 980N.
What is the horizontal distance formula?
The answer depends on the context: If you have a distance vector of magnitude V, that is inclined at an angle q to the horizontal, then the horizontal distance is V*cos(q).
The relationship between resistance and conductors is?
ALL resistance are conductors. just the magnitude value changes

What are the two factors that determine velocity?
The two factors that determine velocity are speed (magnitude of the object's motion) and direction (the path along which the object is moving).
What is the resultant magnitude resultants magnitude and direction if five forces that is 20 kilonewton 15 kilonewton 25 Kille Newton's 30 kilonewton and 10 kilo Newton act from one of the angle point?
To find the resultant magnitude and direction of the five forces acting at an angle, you can resolve each force into its horizontal and vertical components using trigonometry. Then, sum up all the horizontal components and vertical components separately to find the resultant horizontal and vertical components. Finally, use these components to calculate the magnitude and direction of the resultant force using trigonometry.
