Calculate the kinetic energy of a 1000 kg car moving at 4 meters per second
The formula to calculate kinetic energy is:
Kinetic Energy = (1/2) * mass * velocity^2
Given:
Mass (m) = 1000 kg
Velocity (v) = 4 m/s
Now, let's substitute the values into the formula:
Kinetic Energy = (1/2) * 1000 kg * (4 m/s)^2
Multiplying and squaring the velocity:
Kinetic Energy = (1/2) * 1000 kg * 16 m^2/s^2
Solving the multiplication:
Kinetic Energy = 8000 kg m^2/s^2
Therefore, the kinetic energy of the car is 8000 kg m^2/s^2.
To calculate the kinetic energy of an object, you need to use the formula:
Kinetic Energy (KE) = 0.5 * mass * velocity^2
In this case, the mass of the car is 1000 kg and the velocity is 4 meters per second.
Plugging these values into the formula:
KE = 0.5 * 1000 kg * (4 m/s)^2
Simplifying the equation:
KE = 0.5 * 1000 kg * 16 m^2/s^2
KE = 8000 Joules
Therefore, the kinetic energy of the 1000 kg car moving at 4 meters per second is 8000 Joules.
To calculate the kinetic energy (KE) of an object, you can use the following formula:
KE = (1/2) * mass * velocity^2
Given:
Mass of the car (m) = 1000 kg
Velocity of the car (v) = 4 m/s
Now, substitute the given values into the formula to find the kinetic energy (KE):
KE = (1/2) * 1000 kg * (4 m/s)^2
Calculating the values inside the brackets first:
KE = (1/2) * 1000 kg * 16 m^2/s^2
Next, multiply 1000 kg by 16 m^2/s^2:
KE = 500 * 16 m^2/s^2
Finally, calculate the product:
KE = 8000 m^2/s^2
The kinetic energy of the car is 8000 joules (J).
