    Projectile motion where yi doesn't equal yf

    Should Δy be -8.5 instead of regular 8.5? And I don't see where I messed up with the -9.8m/s^2 consistency.

    Projectile motion where yi doesn't equal yf

    I believe so as in the first equation I used: vfy^2= (17⋅sin51)^2⋅-19.6⋅8.5. Is is acceptable for me to have 2g as -19.6, or is that where I am faltering? The solution for vfy=2.818375277; and in the second equation I used: vfy=gt+viy→vfy-viy=gt→(vfy-viy)/g=t. This gives me -10.39310607/-9.8=t...
