Answer:
a)
b)
Explanation:
Let the first ball throw be the point of reference, we can have following the equation of motion:
1st ball: 
2nd ball: 
a)When the 2 balls collide they are at the same spot at the same time:
b) The first ball is at its highest point when v = 0. That is
After this time, the 2 balls would have traveled through a distance of
Since
we can solve for H

Increasing the temperature causes an increase in the average kinetic energy of the particles of a material.
<h3>
What is average kinetic energy of particles?</h3>
The average kinetic energy of particles is the energy possessed by particles due to their constant motion.
The constant motion of particles occurs due to the energy acquired by the particles, when the temperature of the particles increases, the average kinetic energy increases which in turn increases the speed of the particles.
Thus, we can conclude that, increasing the temperature causes an increase in the average kinetic energy of the particles of a material.
