1. A ball is thrown vertically upward with an initial speed of 10m/s from thetop of a building, at a height of 25m from the ground. Assume free fall conditions. a. To what maximum height above the ground does the ball rise? b. With what velocity does the ball strike the ground? c. How long does the ball take to reach the ground? 2. V=v0+at y-y0=v0*t+1/2at^2 3. For the first part (a) i used v=v0+at and plug in my knowns v=0, v0= 10m/s, and i solved for t which came out to be t=1.0 sec. With that i can find my maximum which I plug into the equation y-25=10(1)+(1/2)(-9.8)(1^2) and got the answer 30.1m and for part b and c, I have no clue how to solve it if anyone can help me with a simple problem that be great thanks for the help!
