Rectilinear Motion Problems And Solutions Mathalino Upd

"Find the time it returns to the origin." That means $s(t) = 0$. $t^3 - 6t^2 + 9t = 0$

Let ( t = 0 ) be the start. Car: ( s_c = 0 + 0 \cdot t + \frac12 (2) t^2 = t^2 ) Truck: ( s_t = 10t ) rectilinear motion problems and solutions mathalino upd
