Answer:
John's ball hit the court first
Explanation:
to solve for who hit the court first we have to look for when x was 0
John's ball hit the court in 1 second
now to look for the other guy we substitute 0 to the equation
0 = (-16t - 2) (t - 2)
we cannot substitute 0 to t because its looking for when it hit the court. x is 0 because it hits the ground
soo i guess we distribute ?
or actually we equate both to 0 i think
-16t - 2 = 0 t - 2 = 0
-16t = 2. t = 2
t = 2/-16
t = 1/-8 t = 2
theres two answers but 1/-8 is wrong because theres no such thing as the ball going underground (LOL) so his ball hit the court two seconds later
John's ball hit the court first i think
im not sure how to do the rest, but i do know how to do the first. Sorry but hope this helps you a little!
