What is the kinetic energy of 0.5 kg soccer ball that is travelling at a velocity of 3m/s?
(1/2) m v^2 = (1/2)(1/2)(9) = 9/4 Joules
To calculate the kinetic energy of an object, you need to know its mass and velocity. The formula for kinetic energy is:
Kinetic Energy (KE) = 0.5 * mass * velocity^2
In this case, the mass of the soccer ball is given as 0.5 kg, and the velocity is given as 3 m/s.
1. Start by squaring the velocity: 3^2 = 9
2. Multiply the squared velocity by the mass: 9 * 0.5 = 4.5
Therefore, the kinetic energy of the 0.5 kg soccer ball traveling at a velocity of 3 m/s is 4.5 joules (J).
