Question

An object's velocity as a function of time is given by v(t) = bt - ct^3, where b and c are positive constants with appropriate units. If the object starts at x = 0 at the time t = 0, find expressions for a) the time when it's again at x = 0 and b) its acceleration at that time.

Step 1

Given that v(t) = bt - ct^3, we can set bt - ct^3 = 0. Factoring out t, we get t(b - ct^2) = 0. Since t cannot be zero (as it represents time), we can solve for b - ct^2 = 0. Show more…
