A stone dropped from the second floor of a building? Accelerating or not? explaining?​

Sagot :

Explanation:

During each second, the force of gravity will increase the downward velocity of the stone by approximately 10 m/s.

Therefore, after 6 seconds, the velocity will have gone from zero to 60 m/s.

During that time, the average velocity was 30 m/s.

Now, the easiest way to calculate distance

(if you assume gravitational force remains constant regardless of distance from the center of the Earth, and ignore such things as air friction, wind, ablation, mass changes, radioactive decay, relativistic time-dilation, etc.)

is to simply take the average velocity (30 m/s) and multiply it by time:

30meterssecond×6seconds

= 180meters
