## What is a car of mass 500kg moving with a speed of 36 km h?

Hence, the answer is 1250W. The graph below shows power (P) delivered by the engine of a car as a function of time.

## How do you calculate the kinetic energy of a car of mass 500kg?

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.

## What is a car of mass 1000 kg moving with a velocity of 45km h?

A car of mass 1000 kg moving with a velocity of 45 km/h collides with a tree and comes to stop in 5 s. The force exerted by car is 2500 N. Force = mass × retardation ⇒F=1000 × (2. 5) ⇒F=2500 N The force exerted by the car on the tree is 2500 N.

## 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 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).

## What is the energy of 1kg of mass?

This implies, for instance, that 1 kilogram of matter is equivalent to an energy E = (1 kg)×(3×108 m/sec)2 = 9×1016 kg m2/sec2. An energy of 1 kg m2/sec2 is known as 1 joule, for short.

## 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 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.

## What is the formula for the velocity of a car after collision?

What is the formula of collision? From the conservation of momentum, the formula during a collision is given by: m1v1 + m2v2 = m1v’1 + m2v’2. If the collision is perfectly inelastic, the final velocity of the system is determined using v’ = (m1v1 + m2v2)/m1 + m2.

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

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

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

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

## How to find momentum?

Momentum (P) is equal to mass (M) times velocity (v).

## What is the momentum of a 20 kg body moving with a velocity of 10 m per second?

Hence the momentum of the body is 200 kg. m/s.

## 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.

## What is the KE of a 1 000 kg car Travelling at 60 km h?

Expert-Verified Answer Kinetic Energy of a 1000 Kg car travelling at 60 Km/hrs is 138. 88 J. Explanation: Kinetic Energy of particle of mass, m moving with velocity, v is K.E. = ½mv² .

## 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 momentum of a car of mass 800 kg moving?

A car with a mass of 800. kg moving at 27.8 m/s has a momentum of 2.22 × 10⁴ kg. m/s.
