Finding general solution for y(t): Very Difficult

  1. Mar 17, 2010 #1
    Find y(t) assuming that y(0) = 4000

    2. Relevant equations

    This is what I know!

    v = 20√10 x ((1+Ae^(t/√10))÷(1-Ae^(t/√10)))


    A = -1 when finding particular solution to satisfy initial condition v(0).

    Terminal velocity = 63.246 m.s^-2

    3. The attempt at a solution

    The question states to substitute the solution for velocity into th efollowing equation and solve for y(t).

    y' = v

    I dont really know where to start and have been trying numerous methods help desperatley needed. Thank You

    You mean, the initial condition is v(0) = terminal velocity? If this is correct, then simply integrate v(t) to find y(t) and use the boundary condition to determine the integration constant. Also, I assume the "x" in your definition of v means "times"?

    Firstly yes the 'x' means times sorry bad formatting, second if that is the case how would I go about integrating v(t) to find y(t)?
