Aquarterback throws a football to a teammate. the football is 6.5ft above the ground when it leaves the quarterback's hand. his teammate catches it 3.5s later, at a height above the ground of 5 ft. projectile motion formula h(t) = -16t2 + vt + h0 h0 = 6.5 v = ? h = 5 when t = 3.5 determine the value of v, rounded to the nearest whole number.

v= 56 ft per second

Step-by-step explanation:

Given: A quarterback throws a football to a teammate.

Projectile motion formula is given by :-

, where

Now, to find  v at h=5 and t=3.5, substitute these values in the above equations, we get

the answer is b.)

< 1=< 2

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
