# What is the kinetic energy of a car of mass 500 kg is moving with a velocity of 36 km?

## What is the kinetic energy of a car of mass 500 kg is moving with a velocity of 36 km?

Velocity of car, v = 36 km/hr = 36 × (5/18) = 10 m/s. Mass of car , m = 500 kg. Kinetic energy = (1/2) m v2 = (1/2) × 500 × 10 × 10 = 25000 J = 25 kJ. KInetic energy is proportional to square of velocity .

## What is the momentum of a 1200 kg car with a velocity of 25 m s?

Answer and Explanation: We can find the momentum of the car by multiplying the mass times the velocity. Because both the mass and velocity are given in SI units, we do not need to perform any unit conversion before multiplying. Hence, we have shown that the momentum of the car is 30000 kg m/s.

## 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 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 kinetic energy of a 45 kg object moving at 13?

What is the kinetic energy of a 45 kg object moving at 13 m/sec? 3. Solving the equation gives a kinetic energy value of 3802.5 J. Note: The unit for energy is the same as for work: the Joule (J).

## What is the speed of 500 kg car that has a kinetic energy of 64 kJ?

Kinetic Energy (KE) = 64 kJ = 64 × 103 J. ∴ Speed of the car = 16 m/s.

## 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.

## What is the formula for the maximum velocity of a vehicle car on a banked road?

v=√rg(tanθ+μs)(1−μstanθ) The above equation gives the value of ‘v’, which should be the velocity of a vehicle on the bank for a safe turn. The limiting cases of the above equation can be treated as the maximum velocity of the vehicle on the banked road.

## 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 for momentum with velocity?

p = m v . You can see from the equation that momentum is directly proportional to the object’s mass (m) and velocity (v). Therefore, the greater an object’s mass or the greater its velocity, the greater its momentum.

## What is the momentum of a 1500 kg car?

Therefore p=1500*20 = 30,000 kg m/s.

## What is the kinetic energy of a car of mass 10kg moving with a velocity of 4ms 1?

An object of mass 10 kg is moving with a uniform velocity of 4 ms-1. The kinetic energy possessed by the object is 80 J.

## How do you find the kinetic energy of a moving car?

the kinetic energy of a moving car object is KE=1/2mv^2. create and test a function called KE to find the kinetic energy of a moving car if you know the mass m and the velocity v of the vehicle.

## 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).
