Question: If a 2 kg object is moving with a velocity of 15 m/s, what is its kinetic energy?

Options:

Correct Answer: 225 J

Solution:

Kinetic Energy = 1/2 * m * v^2 = 1/2 * 2 kg * (15 m/s)^2 = 225 J.

If a 2 kg object is moving with a velocity of 15 m/s, what is its kinetic energy?

If a 2 kg object is moving with a velocity of 15 m/s, what is its kinetic energy?

Step 1: Identify the mass (m) of the object. In this case, m = 2 kg.
Step 2: Identify the velocity (v) of the object. Here, v = 15 m/s.
Step 3: Use the formula for kinetic energy: Kinetic Energy = 1/2 * m * v^2.
Step 4: Substitute the values into the formula: Kinetic Energy = 1/2 * 2 kg * (15 m/s)^2.
Step 5: Calculate (15 m/s)^2, which is 225 m^2/s^2.
Step 6: Multiply 2 kg by 225 m^2/s^2 to get 450 kg*m^2/s^2.
Step 7: Now, multiply by 1/2: Kinetic Energy = 1/2 * 450 kg*m^2/s^2 = 225 J.

Kinetic Energy – Kinetic energy is the energy an object possesses due to its motion, calculated using the formula KE = 1/2 * m * v^2, where m is mass and v is velocity.
