to the base of the pipe so the total height would be the stairs + height of top of stairs to the opening of the pipe which is 1.324m

Homework Statement If an object is being launched from the top of a staircase 1.31m high from a pipe 16cm long, at an angle of 60 degrees. Find where the object will land if the initial velocity is 5.442m/s. Homework Equations dx = 2v1^2sinθcosθ / g dy = vyΔt+1/2gΔt^2 dx = vxΔt...

thank you BruceW for the welcome :) so i found drag force to be 7.037N if the marble has a diameter of 15.875mm? So the surface area of the marble is around 0.792m^2 How do i use this? @.@

This is an experiment for school so we can't use real cannons. So we just used a marble and this "cannon" that's made of a pipe and a spring, where we push the spring down and lock it in place with this needle, then release to shoot the marble. I also counted how many spring 'loops?' that i push...

Gr. 11 Projectile motion lab? Homework Statement we are conducting an experiment where a ball is being shot from a cannon from a height of 1.435m we have already calculated our initial velocity, which is 5.442m/s, by timing and measuring when the ball is shot and lands 5 times. Then find...
