Two racing cars cover the same straight track. Car A goes at a constant velocity along the whole

track, while car B starts from rest and maintains a constant acceleration all along the track. The

track length is $460$ m$.$ Both cars finish the track in $210$ s$.$

$($a$)$ Determine the velocity in m$/$s of car A

$($b$)$ Determine the acceleration m$/$s$2$ of car B

$($c$)$ Determine the final velocity in m$/$s of car B
