Kineic energy is the energy that objects posses due to their motion.
KE= 1/2 mv^2
m= mass (kg)
v= velocity (m/s)
KE= Kinetic energy (J)
What is the Kinetic Energy of a 155 kg object that is moving at a speed of 20 m/s?
KE= 1/2 * 155 kg * (20 m/s)^2
KE= 1/2 * 155 kg * 400 m^2/s^2
KE= 31000 kg*m^2/s^2
KE= 31000 Joules
Therefore, the kinetic energy of a 155 kg object moving at a speed of 20 m/s is 31000 Joules.
