The length of the barrel of a primitive blowgun is 1.2 m. Upon leaving the barrel, a dart has a speed of 13 m/s. Assuming that the dart is uniformly accelerated, how long does it take for the dart to travel the length of the barrel?

you first need to find the acceleration from
vf^2=v0^2+2ad
vf=final velocity =13m/s
v0=initial velocity =0
d=1.2 m
a to be found
substitute values and solve for a
once you have a, find the time from
dist = 1/2 at^2 or t=sqrt[2 d/a]
vf^2=v0^2+2ad
vf=final velocity =13m/s
v0=initial velocity =0
d=1.2 m
