Answer:
Step-by-step explanation:
The formula for projectile motion in this case where we're dealing the "American" measure of gravity in feet per second squared, is
where s(t) is the height of the object after a certain amount of time has gone by, v₀ is the initial vertical velocity (our unknown in this case), and h₀ is the initial height.
For us, the initial height is 0 because the ball started off on the ground. What we are being asked is what is v₀, when after 2 seconds have gone by and the ball is 94 feet in the air. 94 feet in the air is the position of the ball, s(t) after t seconds go by. What we are being asked to find then, is v₀ when s(2) = 94
which simplifies to
94 = -64 + 2v₀ and
158 = 2v₀ so
v₀ = 79 feet per second
We have that
<span>(-8)*[10 + (-5) + (-8)]
step 1
</span><span>Multiplying the numbers 10, -5, and -8 by (-8)
[-8*10]+[-8*-5]+[-8*-8]
[-80]+[40]+[64]
step 2
</span><span>adding the three products together
</span>[-80]+[40]+[64]=24
therefore
the answer is
the number is (-8)
Omg ive always wondered about these
