I need to find velocity v from the drawing.
Equations of kinematics
The Attempt at a Solution
I found that v=12.134 m/s . I need to know is it correct.
Delta means this:in order to find your time for s2, you find the time it takes to fall a distance h under gravity with an initial velocity (in the y direction) of zero. This will give you the wrong time. You need to account for the initial vertical velocity. Think: which takes longer to hit the ground: a ball shot straight forward or a ball shot upward at an initial positive angle above the horizontal?I get a different answer.
Maybe you can verbally explain your reasoning?
