A 7.00 kg cannonball is traveling at a velocity of 75.0 m/s at a height of 80.0 m. What is its kinetic energy?(1 point) Responses 19,700 J 19,700 J 39,400 J 39,400 J 525 J 525 J 5500 J 5500 J
The kinetic energy of an object is given by the equation:
Kinetic energy = 1/2 * mass * velocity^2
Plugging in the given values:
Kinetic energy = 1/2 * 7.00 kg * (75.0 m/s)^2
= 1/2 * 7.00 kg * 5625 m^2/s^2
= 19687.5 J
Therefore, the kinetic energy of the cannonball is approximately 19,700 J.
So the correct response is: 19,700 J
