The formula for kinetic energy is KE = 1/2 * m * v^2, where m is the mass of the object and v is its velocity.
Substituting the given values, we get:
KE = 1/2 * 155 kg * (20 m/s)^2
KE = 1/2 * 155 kg * 400 m^2/s^2
KE = 31,000 Joules
Therefore, the kinetic energy of the 155 kg object moving at 20 m/s is 31,000 Joules.
Substituting the given values, we get:
KE = 1/2 * 155 kg * (20 m/s)^2
KE = 1/2 * 155 kg * 400 m^2/s^2
KE = 31,000 Joules
Therefore, the kinetic energy of the 155 kg object moving at 20 m/s is 31,000 Joules.
