Answer:
<em>Both kinetic energies are equal</em>
Explanation:
<u>Kinetic Energy </u>
Is the type of energy of an object due to its state of motion. It's proportional to the mass and the square of the speed.
The equation for the kinetic energy is:
Where:
m = mass of the object
v = speed of the object
The kinetic energy is expressed in Joules (J)
There are two cars:
Car (A) with mass ma=500 kg and speed va= 2 m/s
Car (B) with mass mb=20,000 gr and speed vb= 10 m/s
Calculate the kinetic energy of both cars:
To calculate the Kb, the mass must be expressed in kg:
mb=20,000/1,000 =20 Kg
Both kinetic energies are equal
