Question

an object falling through a fluid is observed to have acceleration given by​

Answer 1

When an object moves with a constant speed, then net acceleration should be zero. This velocity is known as terminal velocity

So, here;

a= g-bv

As, a= 0

g=bv

Therefore

v = g/b (option 1)

Hope you understand

Answer 2

HEYA MATE HERE U GO.

⭐. When velocity becomes constant , acceleration

, a = o

0 = g - bv

bv = g

( or )

v = g /b

Therefore The constant velocity is v = g/b.
