Answer:
Step-by-step explanation:
<u>The depth readings are</u>
- The first mission: - 2 3/4 fathoms
- The second mission: - 2 5/8 fathoms
<u>Comparing the readings</u>
- - 2 3/4 = - 2 6/8 and - 2 5/8
<u>Absolute values compared</u>
Indicating the greater value on the first mission
As per above, the first mission was deeper
First, 9.8 (Gravity) times 3 (time) equals 29.4, which is the velocity after 3 seconds. The kinematic equation for change in position that uses the variables we have is:
delta x= (v)(t) -0.5(acceleration)(time)^2
delta x= 29.4 times (3) - 0.5 (9.8) times 9
delta x= 44.1
100 minus 44.1 equals 55.9, which is the answer for part a.

PART B:
The kinematic equation for this is:
delta x= (initial velocity) times time plus 0.5 (a)(time)^2
100=(0)times(x) plus 0.5 (a)(time)^2
100=0.5(9.8)(x)^2
100=4.9x^2
100/4.9 is approxamitely 20.4.
The squareroot of this is approxamitely 4.5.
4.5 seconds

D. 5x+5y=10
The other 3 could be simplified further and have no y value.
Hope that helps
