In deep space (no gravity), the bolt (arrow) of a crossbow accelerates at 187m/s^2 and attains a speed of 114m/s when it leaves the bow. For how long is it accelerated? Answer in units of m/s

What speed will the bolt have attained 2.8 sec after leaving the crossbow? Answer in units of m/s

How far will the bolt have traveled during the 2.8 sec. Answer in the units of m

  • Physics -

    t=v/a =114/187 = 0.61 s.
    deep space = > v=const => after 2.8 s v= 114m/s,
    Distance = 114.0∙2.8 =319.2 m
