Question
A small, spherical bead of mass 1.9 g is released from rest at t = 0 in a bottle of liquid shampoo. The differential equation of motion
is dv/dt = g−b/m*v .
The terminal speed is observed to be 1.6 cm/s.
The acceleration of gravity is 9.8 m/s2 .
Find the value of the constant b in the
integral form of the above equation
v =mg/b*(1 − e^−b t/m).
Answer in units of Ns/m.
