The height of the tennis ball and the height of the dog's mouth over time would be modelled by: D. h = -16t² + 18t + 4.5 and h = -16t² + 21t + 1.5.

How to model a projectile motion?

In this scenario, the height of the tennis ball and the height of the dog's mouth over time describes a projectile motion because it has a horizontal and vertical component.

This ultimately implies that, we would model this projectile motion by using the quadratic equation (function) given below:

h = -16t² + 18t + 4.5   ....equation 1.

h = -16t² + 21t + 1.5   ....equation 2.
