Answer:
The formula to calculate kinetic energy is:
Kinetic Energy =½ x mass x velocity?
Given:
Mass (m) = 50 kg
Velocity (v) = 20 m/s
Let's plug these values into the formula:
Kinetic Energy = - × 50 kg × (20 m/s≥
Solving this equation:
Kinetic Energy = 2 × 50 × 400 kg • m/s
Kinetic Energy = 10, 000 Joules
Therefore, a 50 kg ball traveling at 20 m/s would have 10,000 Joules of kinetic energy.
