Tan = opposite/adjacent
= 20/15
=4/3
Answer:
12m/s²
Explanation:
Two balls with equal masses and speed engage in a head-on elastic collision. Since the balls of equal mass are moving at equal and opposite speeds, the total linear momentum of the system is zero.
Therefore, the second ball experience an acceleration of 12m/s² at the same time.
Answer:
The Michelson-Morley was designed to detect the motion of the earth through the ether.
No such relation was found and the speed of light is assumed to be the same in all reference frames.
