What is the kinetic energy of an object that has a mass of 4 kg and a velocity of 4 m/sec?
KE = 1/2 mv^2
The kinetic energy of an object can be calculated using the formula:
Kinetic Energy = (1/2) * mass * velocity^2
To find the kinetic energy of an object with a mass of 4 kg and velocity of 4 m/sec, you can substitute these values into the formula and calculate the result.
Here is the step-by-step explanation:
Step 1: Identify the given values:
- Mass (m) = 4 kg
- Velocity (v) = 4 m/sec
Step 2: Substitute the values into the formula:
- Kinetic Energy = (1/2) * mass * velocity^2
- Kinetic Energy = (1/2) * 4 kg * (4 m/sec)^2
Step 3: Simplify the calculation:
- Kinetic Energy = (1/2) * 4 kg * (16 m^2/sec^2)
Step 4: Calculate the result:
- Kinetic Energy = (1/2) * 4 kg * 16 m^2/sec^2
- Kinetic Energy = 32 kg*m^2/sec^2
Therefore, the kinetic energy of the object is 32 kg⋅m²/sec².
