If a 3 kg object is moving with a speed of 4 m/s, what is its kinetic energy?

If a 3 kg object is moving with a speed of 4 m/s, what is its kinetic energy?

Step 1: Identify the mass of the object. In this case, the mass (m) is 3 kg.
Step 2: Identify the speed of the object. Here, the speed (v) is 4 m/s.
Step 3: Use the formula for kinetic energy (KE), which is KE = 0.5 × m × v².
Step 4: Substitute the values into the formula: KE = 0.5 × 3 kg × (4 m/s)².
Step 5: Calculate (4 m/s)², which is 16 m²/s².
Step 6: Now substitute this value back into the equation: KE = 0.5 × 3 kg × 16 m²/s².
Step 7: Multiply 0.5 by 3, which gives you 1.5.
Step 8: Now multiply 1.5 by 16, which gives you 24.
Step 9: Therefore, the kinetic energy (KE) is 24 Joules (J).

Kinetic Energy – Kinetic energy is the energy an object possesses due to its motion, calculated using the formula KE = 0.5 × m × v², where m is mass and v is velocity.
