1. The problem statement, all variables and given/known data Calculate the initial velocity at which water exits the spout of a common drinking fountain 2. Relevant equations V1x=V1cosΘ Θ=tan-1 (opp/adj) V1y=V1sinΘ V2^2=V1^2+2ad 3. 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: V2y^2=V1y^2+2aydy 0=V1y^2+2(-9.8)(8.8) V1y= 13.3 m/s I calculated the angle using the tan formula, so I got: Θ=tan-1(opp/adj) Θ=tan-1 (8.8/6.6) Θ=53 degrees Since I had the angle and V1y, I used these two to get V1x: tanΘ=V1y/V1x V1xtan53=13.3 V1x= 9.89m/s Then I just used the pythagorean theorem to solve for V1. Would my method be correct?
