...okay so, v0 is -5.87

so i used a kinematics equation of: d = ( (vi + vf) / 2) * t

where d is:

d =vi * t + 1/2 * a * t^2

d = -5.87 + 1/2* (9.8)* .0200^2

...and that did not work.

so i found t by using vf + vi/ a .... 0 + 5.87 / 9.8 = t

t = .598979592

okay so i tried to

.....................nevermind its 1.76 meters =D

i just used a different kinematics equation.
