using [tex]\frac{v_0^2}{g_0}=R_{max}[/tex] for this problem:
You buy a toy dart gun and you want to calculate its Max Horizontal Range. You fire the gun straight upward and find that it takes 2.9 seconds for the dart to leave the barrel and then return to the barrel.
Can this be done without the formula. I already tried this:
[tex]V_y=v_{oy}+a_yt[/tex] to find that [tex]v_{oy}=14.21[/tex] I used v_f=0 and t=1.45 to find v_y initial. Now that should be equal to the magnitude of just plain [tex]v_0[/tex] right? or is that a false assumption?
