Modeling with Quadratic Equations

Question 10 • CA-Common Core Math II A-CR

The projectile motion of an object can be modeled usings(t) = gt2 + v0t + s0, where g is the acceleration due to gravity, t is the time in seconds since launch, s(t) is the height after t seconds, v0 is the initial velocity, and s0 is the initial height. The acceleration due to gravity is –4.9 m/s2.

Answer
A
s(t) = –4.9t2 + 39.2
B
s(t) = –4.9t2 + 39.2t
C
s(t) = –4.9t2 + 39.2t + 39.2
D
s(t) = –4.9t2 + 39.2t – 39.2
