## What would be the net force on the car if it were moving to the left?

A)If a car is moving to the left with constant velocity then the net force applied to the car is zero. B) An object cannot remain at rest unless the net force acting on it is zero.

## What acceleration will you give to a 24.3 kg box?

Final answer: The acceleration of a 24.3 kg box being pushed with a force of 85.5 N is approximately 3.52 m/s². This is determined through the application of Newton’s Second Law (F=ma) where acceleration (a) is obtained when the applied force (F) is divided by the mass (m).

## Why does an automobile moving at constant velocity have to keep burning fuel to maintain motion?

Because the rolling friction opposes the motion of the car, it actually subtracts energy from the car. This energy needs to be made up by burning more fuel. A typical sedan has a mass of around 1200 kg.

## When a car moves along a level road at constant speed work is done by the engine?

According to work energy theorem, the work done by the car is zero. Since the kinetic energy does not change and the car is moving along a straight horizontal road the work done is zero only if there is no non conservative force like friction. If there is friction then work done will be force into displacement.

## Why does your body move to the right when you turn left?

Inertia. Your body, like all mass, tries to stay where it is, according to Newton’s first law. If the car turns right, your body tries to stay where it was, which is on the left. Same reason when the car accelerates forwards, you are pushed back into your seat.

## What does Newton’s 2nd law state?

Newton’s second law of motion states that F = ma, or net force is equal to mass times acceleration. A larger net force acting on an object causes a larger acceleration, and objects with larger mass require more force to accelerate.

## How much force is needed to accelerate a 1000 kg car at a rate of 3 m 52?

hence, the force needed to accelerate the 1000kg car by 3m/s2 is 3000N .

## How much net force is required to accelerate 1000 kg car at 4 ms square?

So the net force is required to accelerate a 1000 kg car at 4.00 m/s2 is 4000 N.

## Do you calculate acceleration in kg?

The usual units for acceleration are ms2 . Nkg does not look so much like acceleration. But, if we look at F=m⋅a we will see that 1 Newton, applied to a mass of 1 kg, will cause acceleration of 1 m/s^2. So the Newton is equivalent to kg⋅ms2 .

## What is the formula for the acceleration of a rocket?

Newton’s third law of motion states that to every action, there is an equal and opposite reaction. Acceleration of a rocket is a=vemΔmΔt−g a = v e m Δ m Δ t − g .

## What is the formula for the acceleration of rocket motion?

The acceleration of the rocket can be determined by Newton’s Second Law of Motion. For a constant mass, this law can be written as force (F) equals mass (m) times acceleration (a); (F = m * a). We can solve for the acceleration using algebra ( a = F / m).

## Why a car traveling at a constant velocity while turning right is not accelerating?

For example, if a car turns a corner at constant speed, it is accelerating because its direction is changing. The quicker you turn, the greater the acceleration. So there is an acceleration when velocity changes either in magnitude (an increase or decrease in speed) or in direction, or both.

## What is a car moving with constant speed turning around a curve Class 9?

Hence a car moving at a constant speed and turning around a curve is a uniform circular motion.

## What is a car moving with constant speed turning around a curve answer?

The type of motion that a car exerts while moving with a constant speed and turning around a curve is uniform circular motion and the electron orbitting the nucleus exerts the same kind of motion.

## When a car is moving on a level road and its velocity is doubled?

Answer: (i) The potential energy of the car remains same, since PE (= mgh) is independent of velocity. (ii) The kinetic energy of the car becomes four times, since KE(=1/2 m*v^2) is proportional to square of velocity.

## Is net force to the left negative?

Definition 2: The sum of the forces acting on an object is the net force. If the net force is positive the object moves to the right. If the new force is negative, the object moves to the left.

## What are the forces when a car is moving?

Every vehicle, whether it’s a car, truck, boat, airplane, helicopter or rocket, is affected by four opposing forces: Thrust, Lift, Drag and Weight (Fig. 1).

## Does a moving car have net force?

For a car or any other object to move, it must be accelerated from rest to the desired speed; this requires that the engine force be greater than the friction force. Once the car is moving at constant velocity, the net force must be zero; otherwise, the car will accelerate (gain speed).

## What is the net force acting on the car if a car is traveling with a constant velocity of 20 m s westward?

The resultant force is zero, as the acceleration is zero.
