A ball falls straight down through the air under the influence of gravity. There is a retarding force F on the ball with magnitude given by F = bv, where v is the speed of the ball and b is a positive constant. The ball reaches a terminal velocity after a time t. The magnitude of the acceleration at time t/2 is

Answer:here is ur answer dear
An object is said to be have zero increasing speed, if the adjustment in speed of the question in the given interim of time is zero or the body have consistent speed.
Given :-
a = g - bv ----------------(1)
As per question , after quite a while, the protest have consistent speed/speed, i.e., quickening of the object is zero.
from equation (1) , we get :-
0 = g - vb
v = g/b
