This is a two step problem:(adsbygoogle = window.adsbygoogle || []).push({});

a) In deep space (no gravity), the bolt (arrow) of a crossbow accelerates at 193 m/s2 and attains a speed of 124 m/s when it leaves the bow. For how long is it accelerated?

b) What speed will the bolt have attained 3.6s after leaving the crossbow? Answer in m/s

I correctly figured out that it is accelerated for .642 s. But I don't quite understand what happens afterwards. Since there is no gravity, doesn't the acceleration continue? I multiplied 193 by 3.6 but the answer is wrong.
