## 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.

## Is a 1000 kg vehicle moving with a speed of 20 m per second is brought to rest in a distance of 50 m?

A 1000 kg vehicle moving with a speed of 20m/s is brought to rest in a distance of 50 meters : (i) Find the acceleration. (ii)Calculate the unbalanced force acting on the vehicle. Hence, the unbalanced force acting on the vehicle is -4000N.

## What is the average braking force of a 1000 kg car moving at 10 m s braking to a stop in 5 s?

Answer: The average braking force is 2000 N.

## Can a car moving with a speed of 50 km per hour be stopped?

A car moving with a speed of 50 km/hr, can be stopped by applying brakes after at least 6 m.

## What is braking force formula?

Kinetic energy is given by E = (1/2)mv^2 and Work is W = FS ; hence E = FS thus (1/2)mv^2 = FS ; Thus F = (1/2)mv^2/S. For the given values F = 0.5x 800 x 8.9^2/S = 31684/S. You have to give a value of the breaking distance to be able to find the force needed to stop the car.

## How to calculate velocity?

Determine the object’s original velocity by dividing the time it took for the object to travel a given distance by the total distance. In the equation V = d/t, V is the velocity, d is the distance, and t is the time.

## What is the momentum of 1000 kg car moving northward at 20 m?

p = mv = (1000kg)(20m/s) = 20000 kg m/s, northward • c.

## How much work is required to accelerate a 1000 kg car from 20m * S 1 to 30m S 1?

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

## What is the momentum of a 1200 kg car with a velocity of 25 m s?

Answer and Explanation: We can find the momentum of the car by multiplying the mass times the velocity. Because both the mass and velocity are given in SI units, we do not need to perform any unit conversion before multiplying. Hence, we have shown that the momentum of the car is 30000 kg m/s.

## 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 do you calculate braking rate?

To determine how far the vehicle will travel while braking, use the formula of 1/2 the initial velocity multiplied by the time required to stop.

## What is the momentum of a 2000 kg truck that moves at 10 ms?

Momentum before the collision is p=mv=2000⋅10=20,000 kgms−1 .

## How much work is required to stop a car of 1000 kg moving with speed of 72 km h?

Expert-Verified Answer Work required to stop a car is 400000 Joule or 400 kilojoule.

## How much work is required to stop a car of 1000 kg with a speed of 72 km per hour?

W = 1 2 × 1000 × 20 × 20 = 400000 J.

## Can a car moving with a speed of 60Km h can be stopped?

An automobile travelling with a speed of 60 km/h, can brake to stop within a distance of 20 m. If the car is going twice as fast i.e., 120km/h, the stopping distance will be. Was this answer helpful? An automobile moving with a speed 60kmph can break to stop at a distance 20m.

## What braking force is needed to stop a 1000 kg car?

Conclusion: Therefore, the braking force needed to bring the car at rest is F braking = 2000 N .

## How do you calculate average braking force on a car?

The following formula is used to calculate the braking force of a car given a speed, weight, and stopping distance. To calculate the braking force, divide the mass by 2, multiply by the result of the velocity squared, then divide by the distance.

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

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