A 10 kg object is moving with a velocity of 5 m/s. What is its kinetic energy?

A 10 kg object is moving with a velocity of 5 m/s. What is its kinetic energy?

Step 1: Identify the mass of the object. In this case, the mass (m) is 10 kg.
Step 2: Identify the velocity of the object. Here, the velocity (v) is 5 m/s.
Step 3: Use the formula for kinetic energy, which is KE = (1/2)mv².
Step 4: Substitute the values into the formula: KE = (1/2)(10 kg)(5 m/s)².
Step 5: Calculate the square of the velocity: (5 m/s)² = 25 m²/s².
Step 6: Multiply the mass by the squared velocity: 10 kg * 25 m²/s² = 250 kg·m²/s².
Step 7: Multiply by 1/2: (1/2) * 250 kg·m²/s² = 125 J.
Step 8: Conclude that the kinetic energy of the object is 125 Joules.

Kinetic Energy – Kinetic energy is the energy an object possesses due to its motion, calculated using the formula KE = (1/2)mv², where m is mass and v is velocity.
