A 1,600 kg car is traveling at a speed of 12.5 m/s. What is the kinetic energy of the car?
To find the kinetic energy of the car, we need to use the formula:
Kinetic Energy = 1/2 * mass * velocity^2
In this case, the mass of the car is given as 1,600 kg and the velocity is given as 12.5 m/s.
Plugging in these values into the formula gives us:
Kinetic Energy = 1/2 * 1600 kg * (12.5 m/s)^2
To calculate the squared value, we multiply 12.5 m/s by itself:
Kinetic Energy = 1/2 * 1600 kg * 156.25 m^2/s^2
Now we can simplify the equation by multiplying the values:
Kinetic Energy = 800 kg * 156.25 m^2/s^2
Finally, let's calculate the product of these values:
Kinetic Energy = 125,000 kg * m^2/s^2
The unit for kinetic energy is Joules (J). Therefore, the kinetic energy of the car is 125,000 J.
