apoorvk · Answer

find 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.

The ball ends it's flight when it height reaches 0, right? so $$0=-5t^2+15t$$
