A sprinter in a $100-$m race accelerates uniformly for the first $35$ mand then runs with constant velocity. If the sprinters time for the first$35$ m is $5\mathrm{.}4$ s$,$ determine $($a$)$ his acceleration, $($b$)$ his final velocity,$($c$)$ his time for the race$\mathrm{.}11\mathrm{.}39$ Automobile A starts from O and accelerates at the constant rate of$0\mathrm{.}75$ m$/$s$2.$ A short time later it is passed by bus B$,$ which is traveling inthe opposite direction at a constant speed of $6$ m$/$s$.$ Knowing that busB passes point O $20$ s after automobile A started from there, determinewhen and where the vehicles passed each other.AB AB
