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

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.

When a car moving at 40 km per hour is stopped by applying break?

A car moving with a speed of 40 km//h can be stopped by applying the brakes after at least 2 m. If the same car is moving with a speed of 80 km//h , what is the minimum stopping distance? 40 km//h When braking a fast moving car, it stops at a distance of 4.0 m.

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 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 velocity of a 500 kg car moving with 36km h?

Hence, the answer is 1250W. Was this answer helpful?

What is the formula for speed Ke?

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

W = 1 2 × 1000 × 20 × 20 = 400000 J.

Why if you apply the brakes in a car traveling at 40 mph do you travel 4 times as much distance before stopping than if you had been traveling at 20 mph?

This is because the stopping distance is proportional to its mass times the square of its velocity. Although a car traveling at a speed of 20 mph will take about 20 feet to stop once the driver has pushed the brake pedal, a vehicle going 40 mph will require 80 feet of space to be covered before it ceases moving.

When a car moves with a speed of 40 km for 15 minutes and then with a speed of 60 km?

S1 = 40 km/hr, S2 = 60 km/hr, t1 = t2 = 15 min ⇒ 15/60 = 0.25 hr. Since the journey has variable speed, therefore we have to calculate the distance separately for each case. The total distance covered is D. D = 100 × 0.25 ⇒ 25 km.

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 accelerate a 1000 kg?

The work required to accelerate a 1000 kg car from 20 m/s to 30 m/s is equal to 250,000 joules. The work done can be related by the change in Kinetic Energy: So, 250 KiloJoules of energy/work.

What is the average braking force of a 1000 kg car?

Answer: The average braking force is 2000 N.

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 acceleration?

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).

What is the formula for braking distance?

This formula means that the stopping distance is directly proportional to the square of the speed of the car at the instant the brakes are applied. That is, d ∝ u2 . d = ku2 , where the constant of proportionality k depends on the units being used.

What is the kinetic energy of a car at 60 mph?

4. A 900-kg compact car moving at 60 mi/hr has approximately 320 000 Joules of kinetic energy.

What is the kinetic energy of car having mass 1000 kg?

Kinetic energy of a car, having mass 1000 kg is 1,12,500 J. Driver applies brakes when an obstacle is sighted and car comes to halt after travelling 100 m distance (without meeting with an accident).
