**1. Homework Statement**

A ball is thrown downward with initial speed of 8m/s from a height of 30m.

**2. Homework Equations**

\After what time interval does the ball strike the ground

**3. The Attempt at a Solution**

acceleration will equal -9.8m/s^2 because it's free fall

would i use equation V=Vo-gt

constant speed of a horse is 10m/s. distance from limb to saddle is 3m

A) find horizontal distance between saddle and limb?

B) for what time interval is he in the air?

Attempted solution:

X=Xo+Vo(t)+V2(a)(t^2)

what equation do you use to find the time ... Yf=Yi+Vi(t)+1/2g(t^2) and rearange it to
