**bobpursley**, Tuesday, February 14, 2012 at 4:52pmfigure vertical velocity intial: 42sin45

then, knowing the vertical velocity at the peak is zero...

Vf^2=Vi^2+2gd

figure d

**j**, Tuesday, February 14, 2012 at 4:57pmso does that mean vf is zero, vi is 29.69848481, and g is 9.8

**bobpursley**, Tuesday, February 14, 2012 at 5:03pmg is -9.8m/s^2, so the answer d will be postive, or it should be. Your carrying all those digits on V is nonsense. You are restricted to two significant digits, given the info in the problem.
