Kinetic energy is _____.inversely proportional to mass and velocity directly proportional to mass and velocity directly proporti
2 answers:
Answer : The correct option is, directly proportional to mass and velocity.
Explanation:
Kinetic energy : It is associated with the state of motion of an object.
The formula used for kinetic energy is,
where,
m = mass of an object
v = velocity or speed of an object
From the formula of kinetic energy we conclude that,
The kinetic energy is directly proportional to the mass and the velocity of an object.
Hence, the kinetic energy is directly proportional to mass and velocity.

Answer:
<em>The cantaloupe has a speed of 117.6 m/s</em>
Explanation:
<u>Free Fall Motion</u>
It occurs when an object falls under the sole influence of gravity. Any object that is being acted upon solely by the force of gravity is said to be in a state of free fall. Free-falling objects do not face air resistance.
If an object is dropped from rest in a free-falling motion, it falls with a constant acceleration called the acceleration of gravity, which value is .
The final velocity of a free-falling object after a time t is given by:
vf=g.t
The cantaloupe has been dropped from rest. We are required to find the speed after t=12 seconds.
Calculate the final speed:
vf=9.8 * 12 = 117.6 m/s
The cantaloupe has a speed of 117.6 m/s
