What is the kinetic energy of a 2 kg object moving at a speed of 3 m/s?

What is the kinetic energy of a 2 kg object moving at a speed of 3 m/s?

Step 1: Identify the mass of the object. In this case, the mass (m) is 2 kg.
Step 2: Identify the speed of the object. Here, the speed (v) is 3 m/s.
Step 3: Write down the formula for kinetic energy (KE). The formula is KE = 0.5 * m * v².
Step 4: Calculate v² (the speed squared). So, (3 m/s)² = 9 m²/s².
Step 5: Substitute the values into the formula. KE = 0.5 * 2 kg * 9 m²/s².
Step 6: Multiply 0.5 by 2 kg to get 1 kg.
Step 7: Now multiply 1 kg by 9 m²/s² to get 9 kg·m²/s², which is equal to 9 Joules (J).
Step 8: Conclude that the kinetic energy of the object is 9 J.
