Answer:
The time of motion is 0.64 s.
Explanation:
Given;
mass of the apple, m = 107 g
height of fall, h = 2 m
The velocity of the apple when it hits the ground is calculated from the law of conservation of energy;
The time of motion is calculated;
v = u + gt
6.261 = 0 + 9.8t
6.261 = 9.8t
t = 6.261 / 9.8
t = 0.64 s
Therefore, the time of motion is 0.64 s
The correct answer should be kinetic molecular velocity. Which is a
complex term for the speed of molecules. The faster the molecules move
the more liquid the chemical will be, with the fastest being gaseous
molecules. The slowest ones are things that are solid. This is easily
observed on water that is slowest when ice and fastest when water vapor.
