How much work is done to move a 1400 kg car?

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).

When a 1 kg car and a 2 kg car are both released from the top of the same hill?

Since both cars are released from the same height, they have the same potential energy to start with. Therefore, the car with more mass will have more kinetic energy at the bottom of the hill. So, the 2-kg car will have the greater kinetic energy.

How much work is done to stop a car of weight 1500 kg moving with a velocity 60 km h?

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

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

W = 1 2 × 1000 × 20 × 20 = 400000 J.

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 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.

What is the formula used to calculate the energy that is converted when cars move?

The quantity or amount of kinetic energy is calculated with the following equation: Equation 1. K = 1 2 m v 2 where K represents kinetic energy, m is the mass of the moving object, and v is the velocity, or speed, at which the object is moving.

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 the kinetic energy of a 1500 kg car moving at 20 ms?

Therefore, the kinetic energy of the car is 300,000 J.

What is the kinetic energy of the car with a total mass of 1400 kg is traveling at 30 ms 1?

The kinetic energy of the car of mass 1400 kg at velocity 30 m/s is 630,000 joules. Hence, the kinetic energy of the car of mass 1400 kg at a velocity 30 m/s is 630,000 joules.

How much work is done to stop a car of weight 1500 kg?

Solution: The work required to be done to stop a car of 1500 kg moving at a velocity of 60 km/h is 208333. 3 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.

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.

How do you calculate the force required to move a car?

1. Step 1: Acceleration calculation. As per Newton’s second law. F = ma. a= acceleration of the car. …
2. Step 2: Force calculation. F = ma F = 1500 × 3 F = 4500 Newton. Hence, the force required to impart a car to achieve30 m/s in 10 seconds is 4500 Newton. Suggest Corrections.
