What is the acceleration of car?
Acceleration is the rate of change of velocity as a function of time. For example a car traveling at 50 km/hr starts to accelerate, 10 seconds after, its speed changes to 100 km/hr then the acceleration of the car during the time can be calculated as below: initial speed = 50 km/hr. final speed = 100 km/hr.
What is the power output of the engine of a 1200 kg car?
(II) A 1200 -kg car has a maximum power output of 120 hp.
How much work is done by the engine to increase the speed of the car?
According to the Work-Energy theorem or the relation between Kinetic energy and Work done – the work done on an object is the change in its kinetic energy. Hence, the work to be done to increase the velocity of a car from 30km/h to 60km/h is 156250 joule, if the mass of the car is 1500 kg.
How do you find acceleration in km h?
Calculating acceleration
- first convert km/h to m/s: 100 km/h = 100 ÷ 3.6 = 27.8 m/s.
- then use the values in the equation:
What is the mass of the car?
Mass of a Car

| The Car Book. Washington, DC, 1979: 18. | “It weighs 2500 pounds and gets an EPA rated 28.9 mpg for urban driving.” | 1237.5 kg |
| “Of the automobiles currently on the road, a 400 pound car is twice as safe as a 200 pound car.” | 990–1980 kg |
How do you find acceleration with mass and force?
According to Newton’s second law of motion, the acceleration of an object equals the net force acting on it divided by its mass, or a=Fm. This equation for acceleration can be used to calculate the acceleration of an object when its mass and the net force acting on it are known.
How do you calculate kinetic energy from mass and velocity?
Kinetic Energy. In classical mechanics, kinetic energy (KE) is equal to half of an object’s mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s 2.
What is the kinetic energy of 10 kg?
For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s 2.
How do you calculate the force required to accelerate an 8kg object?
To illustrate, let’s first walk through an example in the metric system, where we’re calculating the force required to accelerate an 8 kg object at 10 m/s2. According to the “F = m a” formula, that force is: F = m a F = (8 kg) (10 m/s2) F = 80 kg m/s2
How does the mass of a car affect acceleration?
If the car is small (i.e. its mass is low) then you won’t have to push as hard (i.e. you can exert a smaller force) to get up to jogging speed quickly (i.e. achieve high acceleration). A Note About “Slugs” When Using the Imperial System for Force, Mass, and Acceleration
