(adsbygoogle = window.adsbygoogle || []).push({}); 1. this is straight out of PHYSICS 8e by cutnell and johnson

chapter 3 page 70

there are two solutions to this equation. one is given by (14 m/s + 1/2 (-9.8 m/s ^2)t = 0 or t = 2.9s

what i cant seem to work out is how did they get t = 2.9s from those calculations

2. y = Voyt + 1/2 ayt^2

3. i just cant seem to calculate the final answer .... do i need to rearrange the equation more ??
