you are playing darts and are wondering how far the dart is dropping on its journey to the target which is 4 m away. The dart leaves your hand at 7 m/s and is accelerating at a rate of -0.3 m/s^2.(adsbygoogle = window.adsbygoogle || []).push({});

work so far...

find final velocity is x-direction from vf^2 = vi^2 + 2ad

vf = 6.8 m/s when dart strikes target

find time it takes to hit target from

vf = vi + at

t = 0.67 s

now, find displacement in y-direction from

d = vit + 1/2at^2

d = -2.2 m

is this correct???

thanks
