Question 1195589: The government wants to test out their new rockets. The path of their rockets are given (measured in kilometers) by h = -0.5d(2d - 500,000). h represents height, and d represents horizontal distance.
a) What is the horizontal distance that the rockets travels?
b) What is the maximum height the rocket flies?

The government wants to test out their new rockets. The path of their rockets are given (measured in kilometers) by h = -0.5d(2d - 500,000). h represents height, and d represents horizontal distance.
a) What is the horizontal distance that the rockets travels?
Assuming the launch and impact are the same height:
h = -d^2 + 250000d = 0
d = 250000 kms - not realistic
====================
b) What is the maximum height the rocket flies?
Max height is the "half-way" point of horizontal distance
h = -(125000)^2 + 250000*125000 = 15625000000 kms - even less realistic

.

It looks like this government believes that the Earth is flat and has the diameter at least 250,000 kilometers.

Thanks for making me laugh.
