Physics 1110, General Physics 1

Instructor: Steven Pollock

There's a lot of good physics in amusement park rides ! Shown here is the first roller coaster in the US to feature a vertical loop. Is there any danger that passengers might fall out at the top? (What if someone's seat belt, or safety bars, wasn't properly fastened?) FYI - at the top of the loop shown, they are going about 45 mph. Look at the picture and try to estimate the radius of curvature [hint: you can see people in the cars, which lets you visually guess the scale]. Then you can figure out the resulting centripetal acceleration at the top. Does your number come out more or less than "g"? What SHOULD it be for a safe ride? If you bring a water bottle with you, and you leave it open, will the water spill out at the top of the loop?
