An object is moving at a squared velocity of 30 m/s. The object has a mass of 4 kg. Find the kinetic energy of the object.
To find the kinetic energy of an object, you can use the formula:
Kinetic Energy = 0.5 * mass * velocity^2
Given that the object has a mass of 4 kg and a squared velocity of 30 m/s, we can substitute these values into the formula to calculate the kinetic energy.
Step 1: Square the velocity
Velocity^2 = 30 m/s * 30 m/s = 900 m^2/s^2
Step 2: Multiply the squared velocity by half the mass
Kinetic Energy = 0.5 * 4 kg * 900 m^2/s^2
Step 3: Calculate the value
Kinetic Energy = 0.5 * 4 kg * 900 m^2/s^2 = 1800 kg*m^2/s^2
Therefore, the kinetic energy of the object is 1800 Joules (J).
