Answer:
The jumper is in freefall for 12.447 seconds.
Explanation:
Let's start by calculating how far the jumper falls.
Initial height (on cliff) = 910 m
Final height after freefall = 150 m
Distance the jumper falls in freefall = 910 - 150 = 760 m
We can now use the equation of motion below to solve for the time:

here. acceleration = 9.81 m/s (due to gravity)
initial speed (u) = 0 m/s (because vertical speed is 0 at the start)
and distance (s) = 760 meters (as calculated above)
So for speed we get:


t = 12.447 seconds
Answer:
The diameter is EF
Explanation:
Given
Circle A (See attachment)
Required
Determine the line that represents the diameter
First, it should be noted that the diameter of a circle is always a straight line.
From the attachment, the circle has the following straight lines:
It should also be noted that the diameter passes through the center of a circle and divides it into two congruent parts.
From the list of straight lines above, only line EF satisfy this property
Hence, the diameter of the circle is line EF.
