Best ResponseYou've already chosen the best response.0By Newton's third law of motion, v^2=u^2+2as where, "v" denotes final velocity, "u" denotes initial velocity, "a" denotes acceleration, and "s" denotes the height attained. Here, "v"=0. Therefore, (u)^2=2as Or, 25*25=2*10*s Or, 625=20s Or, s=625/20=31.25 feet

Best ResponseYou've already chosen the best response.0maximum is given by \[\frac{b}{2a}\] and here \[a=16,b=25\] get \[\frac{b}{2a}=\frac{25}{32}\]

Best ResponseYou've already chosen the best response.0aadarsh the velocity is feet per second and you used m/s for gravity thats the only problem I think

Best ResponseYou've already chosen the best response.0ya, ya!! ur correct. Let me do the correction. Or, 25*25=2*10*10/3*s Or, 625=200/3s( Since, a=10 m/s^2, now, 1m=100 cm, and 30 cm=1 foot, so, 1 m=10/3 feet) Or, 625*3=200s Or, 1875=200s Or, s=1875/200=9.375 feet
