(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

y = -15.2m A golf ball rolls off a horizontal cliff with an initial speed of 11.2 m/s. The ball falls a vertical distance of 15.2 m into a lake below.

(a) How much time does the ball spend in the air?

(b) What is the speed v of the ball just before it strikes the water?

Vox = 11.2 m/s

Voy = 0

ay = -9.8 m/s^2

3. The attempt at a solution

a) y = Voy t + 1/2 ay t^2

-15.2 = 0 + 1/2(-9.8) t^2

t^2 = 3.10

t = 1.76 s

need help working out part b
