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.

The speed of the dart is typically measured in meters per second (m/s) or feet per second (fps) using a chronograph. The chronograph records the time it takes for the dart to travel a known distance, allowing for the calculation of its velocity.
Yes, the length of the barrel can affect the speed of the dart. A longer barrel allows for a longer acceleration time, resulting in a higher velocity and faster dart travel. However, there are other factors such as air resistance and the quality of the barrel that can also influence dart speed.
Different types of darts, such as those made from different materials or with different weights, can have varying travel times. Lighter darts may travel faster due to their lower mass, while heavier darts may have a slower travel time due to their increased inertia. The shape and aerodynamics of the dart can also impact travel time.
Yes, the temperature of the barrel can impact the speed of the dart. A warmer barrel may cause the air inside to expand, resulting in greater air resistance and a slower travel time for the dart. On the other hand, a colder barrel may cause the air inside to contract, resulting in less air resistance and a faster travel time for the dart.
The average travel time for a dart in a standard barrel can vary depending on various factors such as the type of dart, the length and quality of the barrel, and the force with which the dart is propelled. However, it typically ranges from 0.1 to 0.2 seconds for a distance of 1 meter.
