## 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.

## When a 1430 kg car speeds up from rest to 14.0 m s in 7.00 s?

Expert-Verified Answer The power required by the car if a 1430 kg car speeds up from rest to 14.0 m/s in 7.00 s is 20020 Joules.

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

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

## 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 are the 3 formulas for velocity?

- v = u + at.
- v² = u² + 2as.
- s = ut + ½at²

## What are the 4 formulas for velocity?

Variable | Equation |
---|---|

Velocity | v=u+at |

Displacement with positive acceleration | s=ut+21at2 |

Displacement knowing initial and final velocities | s=21(u+v)t |

Velocity squared | v2=u2+2as |

## What is the final velocity formula?

## 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 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 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 car with a total mass of 1400 kg travelling at 30 ms 1?

The kinetic energy of the car of mass 1400 kg at velocity 30 m/s is 630,000 joules. Hence, the kinetic energy of the car of mass 1400 kg at a velocity 30 m/s is 630,000 joules.
