Question

A batter hits a baseball upward with an initial speed of 96 feet per second. After how many seconds does the ball hit the ground? Use the formula h = rt - 16t2 where h represents height in feet and r represents the initial speed

Answer 1

what is h
what is r

Answer 2

0=96t−16t2 do i solve for t ? @10115658

Answer 3

because the height of batter is not given , we can assume it's zero. so apply r = 96 and h=0 to the formula . and solve t

Answer 4

0=96t−16t2 ? @Harindu

Answer 5

t^2

Answer 6

yeah now solve it. there are two values for t one of which is 0

Answer 7

t=6,0 ? @Harindu

Answer 8

yeah thats the correct answer

Answer 9

should it be 0 or 6
