Several species of tuna migrate into the waters off of San Diego every spring. The water temperatures offshore get colder as you move north, and warmer as you move south. The water offshore in the spring is usually about 65 degrees near San Diego.
Albacore tuna prefer colder water (60-68 degrees), bluefin tuna prefer warmer (64-70 degrees), and yellowfin tuna prefer even warmer water (66-80 degrees).
5. In the last 10 years, albacore have moved north to Oregon, bluefin are now here year-round, and yellowfin arrive earlier in the year. What would you infer has happened to water temperatures off of California? What do you think will happen in the future if this trend continues?

Ответ:
6.65m/s
Explanation:
Using the equation of motion
S = ut + 1/2gt²
S is the height of fall
t is the time
u is the horizontal velocity
g is the acceleration due to gravity
Given
S = 300 + 50
S = 350m
t = 7.8seconds
g = 9.8m/s^2
Get S
S = 7.8u + 1/2(9.8)(7.8)²
S = 7.8u + 298.116
350 = 7.8u + 298.116
7.8u = 350 - 298.116
7.8u = 51.884
u = 51.884/7.8
u = 6.65m/s
Hence the rock's horizontal velocity was 6.65m/s
