Question

At a skills competition, a target is being lifted into the air by a cable at a constant speed. An archer standing on the ground launches an arrow toward the target. The system of equations below models the height, in feet, of the target and the arrow t seconds after it was fired. Which statement most likely describes the situation modeled by this system? mc016-1.jpg

Answer 1

From the kinematic equations, s(t) = s_in + (v_in)(t) - (1/2)(g)(t^2). This means that there is an initial distance of 4, initial velocity and acceleration (in opposite direction of the motion) f 32. Option 4 shows the correct answer.
