1. The problem statement, all variables and given/known data a rock is thrown nearly vertical upward from the edge of a tall building of height H. it just misses the edge of the building on the way down and strikes the ground T seconds after being thrown. given H, T determine the initial velocity of the rock the max height it reaches above its starting point the time to reach its max height 2. Relevant equations v= v_0 + at x = x_0 + v_0*t + 1/2*a*t^2 v^2 = v_0^2 + 2a(x - x_0) 3. The attempt at a solution x_0 = H x = 0 v_0 = ? v = ? a = g t = T with these as inputs I don't see how I can manipulate algebra to get the things I want. this is a recurring theme with the rest of my homework it seems: a flowerpot falls off a windowsill and falls past a window below. a person inside the building notices that it takes T seconds to go from the top to the bottom of the window. the window is h meters high. given h, T determine how far above the window is the windowsill. v= v_0 + at x = x_0 + v_0*t + 1/2*a*t^2 v^2 = v_0^2 + 2a(x - x_0) x_0 = 0 x = q + h (figuring out q is the goal) v_0 = 0 v = v a = g t = T one again i feel like when i mess with the algebra i end up going in circles where I can't get everything solved within means of the terms given... hurts my head. i think im doing something fundamentally wrong, let me know.
