Question

The height of an object when projected upward can be described by the equation h=270t−4.9t2, where h is height and t is time. the relationship between the height of the object and the elapsed time is -

Answer 1

For this case we have the following equation:
h = 270t-4.9t2
We observed that:
1) The equation is quadratic
2) The quadratic term of the equation is negative, therefore, the parabola opens downwards.
3) The object is launched with initial height equal to zero.
Answer:
The relationship between the height of the object and the elapsed time is quadratic.
