Final answer:
The Scream Mountain roller coaster has a total of 33 loops, with the highest point being 180 feet above the ground. The number of times the rocket propels the train and the number of loops below 90 feet are not specified in the question.
Step-by-step explanation:
The question you've asked is related to the physics of roller coasters, specifically those with loops like on the Scream Mountain attraction. Here are the answers to your questions:
a) Loops are there in total? There are 33 loops in total on the Scream Mountain roller coaster.
b) Feet above the ground is the highest point in the track. The highest point is 180 feet above the ground.
c) Times does the rocket propel the train? This information is not provided in the question, so I'm unable to give a specific answer.
d) Loops are below the 90 feet high loop. This is again not specified in the question, but we know there is at least one loop that is 180 feet, so other loops could be any height up to 180 feet.
