For this activity I had to find out the minimum height for the stratosfear, then give a reason why I think there is a height restriction. There are two modes to the stratosfear: the less extreme (45 degree swing angle) and the very extreme (360 degree swing angle). Here are the height restrictions:
Less Extreme height restriction
130 cm to go on this mode
Very Extreme height restriction
150 cm to go on this mode
I think there is a height restriction because your seat belt might be loose and you could fall off and being able to reach the height restriction could prevent you from hazards similar to that.
