Calculate the initial velocity at which water exits the spout of a common drinking fountain
V1x=V1cosΘ Θ=tan-1 (opp/adj)
The Attempt at a Solution
I measured the total distance travelled by the water in the x-direction (dx), and I got 13.2 cm. I also measured the maximum height and got 8.8cm. I used the kinematic formula (V2y^2=V1y^2+2aydy), so I had:
V1y= 13.3 m/s
I calculated the angle using the tan formula, so I got:
Since I had the angle and V1y, I used these two to get V1x:
Then I just used the pythagorean theorem to solve for V1. Would my method be correct?
