Best ResponseYou've already chosen the best response.0find the two times when height "h" is zero. equate the equation to zero for that. now the smaller 't' will be the time when the ball was launched and the larger 't' value wil be the time when the ball landed. deduct the two to get the Time Period.

Best ResponseYou've already chosen the best response.0The ball ends it's flight when it height reaches 0, right? so \[0=5t^2+15t\]

Best ResponseYou've already chosen the best response.2i would say there are to many assumptions to be had in order to make a proper determination

Best ResponseYou've already chosen the best response.0That's actually just one of the questions. These are all of them: a)Find the time of flight of the golf ball b)Draw the graph of h=5t^2+15t during the time of flight c)Find the maximum height of the golf ball from the ground d)when is the golf ball 8m above the ground?

Best ResponseYou've already chosen the best response.0Yes, but you know the height from the ground, I suppose it's the ground directly beneath the ball.

Best ResponseYou've already chosen the best response.0It doesn't have to be straight up.

Best ResponseYou've already chosen the best response.0You know only the height, you don's know where it is.

Best ResponseYou've already chosen the best response.2a)Find the time of flight of the golf ball h(t) = 0 b)Draw the graph of h=5t^2+15t during the time of flight draw an upside down parabola using the zeros found above and the vertex found in "c" c)Find the maximum height of the golf ball from the ground the vertex IS the high point d)when is the golf ball 8m above the ground? when h(t) = 8

Best ResponseYou've already chosen the best response.0well ofcourse a lot of assumptions are required, but when nothing's been stated, we take the simplest factors into account, i believe.
