The discussion focuses on calculating the time it takes for a dart to travel the length of a 1.5-meter barrel of a primitive blowgun, given that it exits the barrel at a speed of 12 m/s and is uniformly accelerated. The initial approach using the formula t = d/v was incorrect due to the assumption of constant speed rather than acceleration. The correct method involves determining the acceleration first, as the dart starts from rest, and then applying kinematic equations to find the time taken.
PREREQUISITESThis discussion is beneficial for physics students, educators, and anyone interested in understanding the principles of motion and acceleration in practical scenarios.

The length of the barrel of a primitive blowgun is 1.5 m. Upon leaving the barrel, a dart has a speed of 12 m/s. Assuming that the dart is uniformly accelerated, how long does it take for the dart to travel the length of the barrel?
Homework Equations
I was thinking of using t=d/v.The Attempt at a Solution
So it might be t=1.5/12
t= .125 s? but that doesn't sound right at all.
