2) acceleration, a = 9.8 m/s^2

3) time up = time down = 4seconds / 2 = 2 seconds

4) formula = Vf = Vo - a*t^2/2

Vf = 0 => Vo = a*t^2 / 2 = 9.8m/s^2 * (2 s)^2 / 2 = 19.6 m/s

alukav5142 [94]

Answer:

Answer: (B) 3

Step-by-step explanation:

20x + 15(2x) + 10(3x) = 40

20x + 30x + 30x = 40

80x = 40

x = 40/80

x = 1/2

Find the amount of lobster

Lobster = x = 1/2 pound

Find the amount of crab:

Crab = 2x = 2(1/2) = 1 pound

Find the amount of Shrimp:

Shrimp = 3x = 3(1/2) = 3/2 pounds

Find the total pounds of seafood:

Total = 1/2 + 1 + 3/2 = 3 pounds

Answer: (B) 3
