Question 150243
a general trajectory related formula for baseballs, golf balls, artillery shells, etc.
__ is h=-16t^2+(Vo)t+Ho __ h is the height at time (t), Vo is the initial upward (vertical) velocity
__ and Ho is the initial height


for part a), you need to find the time (t) when h=0 (return to Earth)


0=-16t^2+150t+5 __ use the quadratic formula to find t
__ HINT __ the positive value is the one you want


other HINT __ max height is approx 357'
