Question

Alice kicks a soccer ball with a mass of 2 kg. The ball leaves the ground moving 30 meters per second. What is the kinetic energy of the soccer ball? (KE = 1/2mv2)I

Answer 1

By using the formula:

• K.E = ½mv²

• mass, m = 2 kg
• Velocity, v = 30 m/s

→ K.E = ½ × 2 × (30)² J

→ K.E = (30)² J

→ K.E = 900 J (Answer)
