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

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

Answer: Work required to stop a car is 400000 Joule or 400 kilojoule.

## What is the KE of a 1000 kg car traveling at 60 km h?

Calculate the kinetic energy: KE = 0.5 * 1000 kg * 277.78 m^2/s^2 = 138890 J (Joules) So, the kinetic energy of the car is 138,890 Joules.

## What is said to be done to increase the velocity of a car from 15 km per hour to 30 km per hour if the mass of the car is 1000 kg?

W=? ∴ Work done =337500 Joule.

## What is the amount of work required to stop a car 1000 kg moving with a speed of 72 km per hour?

W = 1 2 × 1000 × 20 × 20 = 400000 J.

## 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 the kinetic energy of a car of mass 1000 kg moving at 20 ms 1?

By using the equation: Kinetic Energy = (1/2)mv^2, using m as 1000kg and v as 20ms^-1. We can calculate this value as follows: KE = (1/2)(1000)(20)^2This is equal to 2.0*10^5J (solved using a scientific calculator).

## What to be done to increase the velocity of a car from 30 km per hour to 60 km per hour if the mass of the car is 1500 kg?

1. Answer: Work done is 156250 J.
2. Explanation: Given, The mass (m) of the car is 1500 kg. Initial velocity of car = u = 30 km / hr = 30 * 5/18 = 25 / 3 m/s. …

## What is an increase in a car’s velocity called?

Acceleration is the name we give to any process where the velocity changes. Since velocity is a speed and a direction, there are only two ways for you to accelerate: change your speed or change your direction—or change both.

## What is the speed of a car moving at 50 km per hour returns on the same route with a speed of 40km hr?

Average speed=1+1(1/50)+(1/40)=44.44m/s.

## How do you stop a 1500 kg car from moving?

## 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 work is done to move a 1400 kg car?

Hence, the work done against the friction =20300 J. A car weighing 1400 kg is moving at a speed of 54 km/h up a hill when the motor stops. If it is just able to reach the destination which is at a height of 10 m above the point, calculate the work done against friction (negative of the work done by the friction).

## How much work must be done to stop a 1000kg?

In summary, the conversation discusses the problem of finding the amount of work needed to stop a 1000kg car traveling at 100km/h. The individual suggests converting the speed to m/s and using the standard formula for energy to solve the problem. The final answer is 3.858 x 10^5 J.
