Quadratic Function for Projectile Motion
Which of the following quadratic functions models the height of a marble thrown upward with an initial velocity of 10 meters per second from an initial height of 2 meters?
Af(t) = -4.9t^2 + 10t + 2
Bf(t) = -49t^2 + 20t + 4
Cf(t) = -16t^2 + 10t + 2
Df(t) = -16t^2 + 100t + 20
Ef(t) = -4.9t^2 + 2t + 10
