Hi everyone. It seems I've forgotten how to solve this one. I was wondering if someone could help me remember how.
Think projectile motion, straight up/down no resistance. I point out the part I have a problem with near the end. (this is all in accordance with a book on applied mathematics.)
d2x/dt2= -g initial conditions are dx/dt=v0 x(0) = 0
x(t) = -1/2*g*t2 + v0 *t
The book makes says that I can solve for t to get
t=v0/g - how?
and then realize the next equation without any explanation.
Xmax= v02/2g - how?
I would be very grateful for help and direction on this one. Thanks.
