Homework Statement
In an experiment to determine the viscosity of some oil, a ball is dropped into some oil. The position of the ball is given by the formula y=Y+At+Be-Ct. At t=0, y=0.070 m, the velocity dy/dt is 0 and the acceleration is 0.0983 m/s2. As t→∞ the velocity approaches 0.480 m/s. What is the value of Y in MKS units?
Homework Equations
y=Y+At+Be-Ct
vy(t)=A+-CBe-Ct
ay(t)=C2Be-Ct
The Attempt at a Solution
With four unknowns (Y,A,B,C), I came up with three equations:
B+Y=0.070m
A=CB
BC2=0.0983
I wasn't sure what to do as t→∞
