Suppose represents a person’s bank account balance. The units of x would be dollars ($) , and velocity ? would give the rate at which the balance changes (in units of, for example, $/month). Acceleration would give the rate at which ? changes. Suppose a person begins with ten thousand dollars in the bank. Initial money management leads to no net change in the account balance so that ? = 0 . Unfortunately, management worsens over time so that ? = −250$/????h . Assuming ? is constant, find the amount of time in months until the bank account is empty.
