## 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.

## How can a car moving with a velocity of 10 Metre per second be stopped?

A car moving with velocity of 10m/sec can be stopped by application of a constant force F in a distance of 20m.

## How does hitting a barrier change momentum?

The concept of impulse is highly useful in activities that involve forces acting on a short period such as when a car suddenly hits a barrier or when a baseball hits a bat. A large force exerted on a short period allows the ball to experience a change in momentum.

## 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 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.

## 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.

## How much force is required to stop a bus in 10 seconds of mass?

Expert-Verified Answer Force used to stop the bus = mass of the bus in kg× deceleration = 5000 kg× – 2 m/s² = – 10,000 N. The minus sign implies force is supplied by the decelerating agency.

## What do you mean by acceleration of a moving vehicle is 10 Metre per second?

Explanation: Acceleration is the rate of change of velocity of a body w.r.t time. Thus, if the acceleration of a body is 10m/s^2 , it means that the body accelerates after every second with a velocity of 10m/s.

## Can we stop a fast moving car instantaneously explain?

No, we cannot instantaneously stop a fast moving automobile as it requires sudden change in momentum which is not possible. Changing momentum is a gradual process as it requires force to act over a period of time.

## How do crash barriers work?

Crash barriers, including Armco barriers are actually designed to deform to an extent. When impacted by a vehicle, these barriers will actually bend and crumple before they snap! This is for a few reasons: To reduce g-force by preventing the vehicle from coming to a hard stop instantly on collision.

## How do crash barriers reduce force?

The design specifically achieves this by diverting the energy from any impact to the base of the barrier, where it stabilizes the barrier and redirects the vehicle back onto the roadway and away from the barrier – vital on those vulnerable roadsides where an errant vehicle coming off the road could lead to additional …

## What is the SI unit of momentum?

Momentum | |
---|---|

SI unit | kilogram meter per second (kg⋅m/s) |

Common symbols | p, p |

Other units | slug⋅ft/s |

Dimension | MLT^{−}^{1} |

## 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 do you find the net force of a car?

- F is the net force.
- m is the mass of the object.
- a is acceleration.

## What is the net force of a car moving at constant velocity uphill?

Regardless of the direction, if an object has uniform velocity (moving with the same speed in one direction) the net force on the object will be zero.

## 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.

## What is the work done by brakes of a car of mass 1000 kg when its speed reduced from 20 Metre per second to 10?

Therefore, work done by the brake to reduce the speed will be equal to the change in kinetic energy of the car. Therefore, work done by the brakes will be 1.5×105 J 1.5 × 10 5 J .

## What is 10000 n of braking a 2000 kg truck stops in 6 seconds?

With 10,000 N of braking, a 2000 kg truck stops in 6 seconds. The truck’s speed before braking was what? The trucks speed before braking was 30 m/s (10000/2000=5 (5*6=30).
