Answer:
a = -16.9 ft/s²
Explanation:
81.8 mi/hr(5280 ft/mi / 3600s/hr) = 120 ft/s
a = Δv/t = (0 - 120) / 7.1 = -16.9 ft/s²
if the initial direction is taken as the positive direction.

Answer:
The answer to your question is 75 cm²
Explanation:
To solve this problem, we need to use the Pascal's principle that states that the pressure in a point is equal to the pressure in a second point.

Process
1.- Solve for A2

2.- Substitution

3.- Simplification and result

A2 = 75 cm²
