Homework Statement
A ball is thrown downward with initial speed of 8m/s from a height of 30m.
Homework Equations
\After what time interval does the ball strike the ground
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
