Answer:
continuous change in position with respect to time
Explanation:
Velocity is defined as the rate of change of the position of an object with respect to its time.
It's the vector quantity of speed as it has both magnitude and direction.
Hope this helps :)
B.) Carbon Dioxide because the carbon is surrounded by oxygen
Supposing the runner is condensed to a point and moves upward at 2.2 m/s.
It takes a time = 2.2/g = 2.2/9.8 = 0.22 seconds to increase to max height.
Now looking at this condition in opposite - that is the runner is at max height and drops back to earth in 0.22 s (symmetry of this kind of motion).
From what height does any object take 0.22 s to fall to earth (supposing there is no air friction)?
d = 1/2gt²= (0.5)(9.8)(0.22)²= 0.24 m
