Assignment:
Blow gun
Using only a meter stick, brains and a calculator, find
1. Vi (coming out of the gun) muzzle velocity, (Hint:first find time)
2. Vfy (a vector)
3. Vf (a vector) When it hit the cardboard, magnitude and direction (Hint: use vfy and the pythagorean theorem)
4. Find a in the gun (length of gun = 1.38 meters)
5. Find t in the gun (length of gun = 1.38 meters
6. Find the angle that you would have to shoot it at (assuming the same Vi) in order to hit me between the eyes. (This is not the same angle as in 3.)
x = 9.0 meters
Δy = 0.170 meters
A dart was shot horizontally out of a blow-gun whose length is 1.38m, and was intended to hit a target 9.0m away (a picture of a person right between their eyes). Upon impact the dart hit 0.170m below its target. Find the 6 components asked for above.
Provide complete and step by step solution for the question and show calculations and use formulas.
