Initially when ball is thrown up in air, its kinetic energy goes on decreasing. This loss in kinetic energy changes in potential energy and it keeps on increasing. This potential energy becomes maximum at highest point of its motion. At this highest point, kinetic energy of ball becomes zero. Now while coming down, potential energy goes on decreasing and this loss changes into kinetic energy. This kinetic energy keeps on increasing till it hits the ground or stopped by some external agent. Hope it helps.
Heat in a system can be calculated by multiplying the given mass to the
specific heat capacity of the substance and the temperature difference. It is
expressed as follows:<span>
Heat = mC(T2-T1)
Heat = 100(1)(60-20)
<span>Heat = 4000 calories addition to the system</span></span>

Answer:
They hit the ground at the same time
Explanation:
Mass doesn't matter in free fall. As long as they were released with the same velocity and the same height, they'll hit the ground at the same time
