## 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 a car with a mass of 1500 kg is driving at 20 ms?

Expert-Verified Answer The kinetic energy of a car with a mass of 1,500 kg driving at 20 m/s is 300,000 J.

## How much work is done to stop a car weighing 1500 kg moving with a speed of 60 km h?

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

## 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 is the momentum of 1000 kg car moving northward at 20 m?

p = mv = (1000kg)(20m/s) = 20000 kg m/s, northward • c.

## What’s the formula for kinetic energy?

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

## How to calculate velocity?

Determine the object’s original velocity by dividing the time it took for the object to travel a given distance by the total distance. In the equation V = d/t, V is the velocity, d is the distance, and t is the time.

## What is the formula for a car of mass 1500 kg rounds a curve of radius 250m at 90 km hour?

=1500×(25)2250=3750N.

## What is momentum class 9?

Momentum is the quantity of motion of a moving body, measured as a product of its mass and velocity. it formula = mass velocity.

## What is the work to be done to stop a car of 1500 kg moving at a velocity of 16 km per hour?

∴ The work done to stop the moving car = 208333 J.

## 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.

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

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

## Does velocity mean speed?

Why is it incorrect to use the terms speed and velocity interchangeably? The reason is simple. Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement.

## How to find momentum?

Step 1: List the mass and velocity of the object. Step 2: Convert any values into SI units (kg, m, s). Step 3: Multiply the mass and velocity of the object together to get the momentum of the object.

## What is the formula of total energy?

Total Energy is defined as: E=γmc2 E = γ m c 2 , where γ=1√1−v2c2 γ = 1 1 − v 2 c 2 . Rest energy is E0=mc2 E 0 = m c 2 , meaning that mass is a form of energy. If energy is stored in an object, its mass increases.

## What is the kinetic energy of a 1500 kg car traveling at a speed?

The kinetic energy for a moving object is given by the equation, KE = 0.5 * m * v², where ‘m’ is mass and ‘v’ is velocity. Therefore, for the car mentioned a) kinetic energy would be equal to 0.5 * 1500 kg * (30 m/s)² = 675,000 Joules or 675 kJ.

## What is the kinetic energy of a 1000 kg car has a velocity of 17 mm per second?

Answer. The kinetic energy of the car is 144, 500 Joules.

## What is the kinetic energy of a 1000 kg roller coaster car that is moving with a speed?

Expert-Verified Answer The kinetic energy of the roller coaster at the given mass and speed is 200,000 J. The given parameters; mass of the roller coaster, m = 1000 kg. speed of the roller coaster, v = 20 m/s.

## What is the kinetic energy of a car weighing 12 kn has a speed of 20m s?

K=[(1/2). 12×10^2. (20)^2] J = 2.4×10^5 J. Thus the required kinetic energy of the car is 2.4×10^5 J = 240kJ.
