## What braking force is needed to bring a 2200 kilogram car going 18 meters per second to rest in 6.0 seconds?

F = 2200 × ( – 3 ) = – 6600 N .

## How does the mass of your car affect its motion?

Weight affects speed down the ramp (the pull of gravity), but it’s the mass (and friction) that affects speed after a car leaves the ramp. Heavier cars have more momentum, so they travel further, given the same amount of friction.

## What is the momentum of a car with a mass?

Answer and Explanation: The momentum of a parked car is zero because only objects that are in motion can have momentum. Momentum is a measure of how much motion an object has. This can be seen in the formula for momentum, which is as follows: p = mv, where p = momentum, m = mass and v = velocity.

## What is the acceleration of a truck with a mass of 2000kg?

An unloaded truck weighing 2000 kg has a maximum acceleration of 0.5 m / s 2 .

## What is the formula for acceleration of a moving car?

Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.

## How much force is required by a car of mass 1000 kg starting from rest to gain a velocity of 30 metre per second?

Thus, force required is 4500 N.

## How much net force is required to accelerate a 3000 kg car at 2.00 m s2?

Force = mass * acceleration = m * a = 3000 * 2 = 6000 Newton.

## What is the average braking force of a 1000 kg car moving at 20m s?

Therefore, the force applied by the brakes is 2000 N. Q. A car of mass 1000 kg moving with a velocity of 20 m/s is brought to rest by applying brakes in 10 seconds.

## What is Newton’s second law called?

According to Newton s Second Law of Motion, also known as the Law of Force and Acceleration, a force upon an object causes it to accelerate according to the formula net force = mass x acceleration. So the acceleration of the object is directly proportional to the force and inversely proportional to the mass.

## What are the 4 forces of a car?

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).

## What is Newton’s second law of pushing a car?

The second law: When a force is applied to a car, the change in motion is proportional to the force divided by the mass of the car. This law is expressed by the famous equation F = ma, where F is a force, m is the mass of the car, and a is the acceleration, or change in motion, of the car.

## How much work is required to accelerate a 1000 kg car from 20 ms to 30 ms?

The work required to accelerate a 1000 kg car from 20 m/s to 30 m/s is equal to 250,000 joules.

## How much work is done to stop a car weighing 1500 kg moving with a speed of 60 km h?

Hence, work required to stop the car =12×1500×16.662 =208166.7J=208.17kJ. Was this answer helpful?

## How much net force is required to accelerate a 2000 kg car?

Force is defined as the product of the mass and acceleration of the body. Force is used to changing the velocity that is to accelerate an object or a body of a particular mass. The unit of Force is Newton or kg m/s^2. Thus, to accelerate the car at 3.00 m/s^2 of mass 2000 kg net force required is 6000 N.

## How much net force is required to accelerate a 1000kg car at 4m s 2?

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