Hi,
Im having a problem solving one part of a question..
1) A ball is thrown upward with the initial velocity of 80 m/s.
a- How long is the ball in the air? 16.33s
b- What is the greatest height reached by the ball? 326.26m
c- when is the ball 20m above the ground?
I think I am doing this wrong, but I put 20 = v_0*t, 20/V_0 = t and i get 0.25s
d- what is the velocity of the ball, when it hits the ground?
On this one I am totaly lost, but I managed to get sqrt(2g+v^2+h) which I know is wrong.
I think a and b are correct but I am not so sure about the c and d, If you can read over it and see if it right I would appreciate it..
Thank You.
