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

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

## When velocity of a body is increased 5 times what is the change in its kinetic energy?

Whenever the velocity is increased five times, the velocity is 5 v. Kinetic energy is known as EK. Therefore, When the velocity is increased by 5 times, the kinetic energy increases by 25 times.

## When a 1.53 kilogram mass is placed on a spring?

When a 1.53-kilogram mass is placed on a spring with a spring constant of 30.0 Newtons per meter, the spring is compressed 0.500 meter.

## What is a roller coaster car has a mass of 290 kg starting from rest the car acquires?

A roller coaster car has a mass of 290. kilograms. Starting from rest, the car acquires 3.13 x 105 joules of kinetic energy as it descends to the bottom of a hill in 5.3 seconds.

## 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 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 .

## What is the formula of change in velocity of a body?

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). Acceleration is also a vector quantity, so it includes both magnitude and direction. Created by Sal Khan.

## When velocity of a body is increased 3 times what is the change in its kinetic energy?

Hence, new kinetic energy becomes 9 times.

## Is kinetic energy change in velocity?

Kinetic energy depends on the velocity of the object squared. This means that when the velocity of an object doubles, its kinetic energy quadruples.

## What is K in spring-mass?

It’s used to determine stability or instability in a spring, and therefore the system it’s intended for. As a formula, it reworks Hooke’s Law and is expressed through the equation: k = – F/x. Where k is the spring constant, F is the force applied over x, and x is the displacement by the spring expressed in N/m.

## What objects has the most inertia?

Inertia is the resistance offered by an object to any change in its state of motion, or even change in its direction of motion. It depends upon mass of the body. More the mass of body, more is the inertia. Therefore, truck has more inertia as compared to other given options.

## Is spring constant in G or KG?

What are spring constant units? In SI units, displacements are measured in meters (m), and forces in newtons (N or kg. m/s2). Therefore, the spring constant k, and each element of the tensor κ, is measured in newtons per meter (N/m), or kilograms per second squared (kg/s2).

## 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 acceleration of a car with a mass of 1 200 kg?

In this case, the mass of the car and the force exerted on it are provided as information. Therefore, the acceleration of the car is 0.5 m s−2 when its engine exerts a force of 600 N .

## 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).

## How much work must be done to stop a 1000 kg car Travelling at 100km * H 1?

Hence, 385864 J work must be done to stop a traveling car.

## 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 work required to be done to stop a car of 1200 kg moving with a velocity of 54 km per hour?

Expert-Verified Answer Thus the Work required to stop the car is -135,000 Joule or -135 kilo Joule.

## What is the work required to stop a car of 1500 kg moving at a velocity of 72km hr?

Hence, 30×104 J of work is required to stop the car. Q. Calculate the work required to be done to stop a car of 1500 kg moving at a velocity of 72 kmph?
