Oh no I hope you figured out the answer to this! If not, here's a quick run-down
Given: a, vi, d
Need: vf
Equation that matches: vf2 = vi2 + 2ad
vf2 = 02 + 2*(1.7)*(5.5)
vf2 = 18.7 m2/s2
vf = 4.3 m/s
If all else fails, remember to draw out a chart with what you know and what you don't know, then you can figure out which equations on your formula sheet might be helpful :)
