Answer:
49 m/s
Step-by-step explanation:
We don't know what your model is, so we'll solve this based on the balance of forces. Air resistance exerts an upward force of ...
(4 N/(m/s))v
Gravity exerts a downward force of ...
(20 kg)(9.8 m/s²) = 196 N
These are balanced (no net acceleration) when ...
(4 N/(m/s))v = 196 N
v = (196 N)/(4 N/(m/s)) = 49 m/s
The terminal velocity is expected to be 49 m/s.
He is incorrect because if a number is before a letter than the number is the coefficient. and the coefficient is always multiplied by the letter its next to. since f is being distributed to x (multiplied because of the parentheses) then fx=3x which means f = 3 which means 3x=3x
