Sagot :
By assuming that the motion of the plastic disc thrown by Mary is a projectile motion, the missing values are 4 and 3 respectively.
How to determine the missing height?
Since we're assuming that the motion of the plastic disc thrown by Mary is a projectile motion, it simply means that the motion can be represented by a quadratic function (parabolic).
For a projectile motion, the height of the disc at the time when it's at the top would be the same (equal). Thus, we can logically deduce that:
Height at time (t = 1 seconds) = Height at time (t = 5 seconds)
4 = A.
Similarly, Height at time (t = 0 seconds) = Height at time (t = 6 seconds)
3 = B.
