Answer:
A im pretty sure
Step-by-step explanation:
The total time of flight of a projectile motion is calculated through the equation,
t = 2v₀sinФ/g
Substituting the known values,
t = (2)(12 m/s)(sin 90)/9.8 m/s²
t = 2.45 s
Thus, the total flight time of the ball in the atmosphere is 2.45 s.
Answer:
C or the 3rd one
Step-by-step explanation:
Because you know the amount of rings bought but not how much shirts cost
=x^2-8x+16-16
= (x-4) ^2-16
=[(x-4) -4][(x-4) +4]
=(x-8) x
