<span>a) 1960 m
b) 960 m
Assumptions.
1. Ignore air resistance.
2. Gravity is 9.80 m/s^2
For the situation where the balloon was stationary, the equation for the distance the bottle fell is
d = 1/2 AT^2
d = 1/2 9.80 m/s^2 (20s)^2
d = 4.9 m/s^2 * 400 s^2
d = 4.9 * 400 m
d = 1960 m
For situation b, the equation is quite similar except we need to account for the initial velocity of the bottle. We can either assume that the acceleration for gravity is negative, or that the initial velocity is negative. We just need to make certain that the two effects (falling due to acceleration from gravity) and (climbing due to initial acceleration) counteract each other. So the formula becomes
d = 1/2 9.80 m/s^2 (20s)^2 - 50 m/s * T
d = 1/2 9.80 m/s^2 (20s)^2 - 50m/s *20s
d = 4.9 m/s^2 * 400 s^2 - 1000 m
d = 4.9 * 400 m - 1000 m
d = 1960 m - 1000 m
d = 960 m</span>
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected.

50 mph = 50 miles in one hour
300 divided by 50 = 6 hours
Answer:
Impairs one's ability to function
Explanation:
Answer:
F = 1200 N
General Formulas and Concepts:
<u>Forces</u>
Newton's Second Law of Motion: F = ma
- F is force (in N)
- m is mass (in kg)
- a is acceleration (in m/s²)
Explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
<em>m</em> = 300 kg
<em>a</em> = 4 m/s²
<u>Step 2: Find Force</u>
- Substitute in variables [Newton's Second Law of Motion]: F = (300 kg)(4 m/s²)
- Multiply: F = 1200 N
