Variation in your apparent weight is desirable when you ride a roller coaster; it makes the ride fun. However, too much variation over a short period of time can be painful. For this reason, the loops of real roller coasters are not simply circles like (Figure 1) . A typical loop is shown in(Figure 2) . The radius of the circle that matches the track at the top of the loop is much smaller than that of a matching circle...

You are designing the section of a roller coaster ride shown in the figure. Previous sections of the ride give the train a speed of 14.9 m/s at the top of the incline, which is 38.3 m above the ground. As any good engineer would, you begin your design with safety in mind. Your local government's safety regulations state that the riders' centripetal acceleration should be no more than n 1.57 g at the top of the hump and no...

3. Wanting to show your friends a cool demonstration that seems to break the laws of physics, you swing a pail of water in a vertical circle. You swing the bucket a couple times, no water comes out at the top, and complete each circle in 1.5 seconds. If your arm length is 60 cm and the bucket/water have a mass of 1.00 kg, determine...

Problem #3 You've taken your neighbor's young child to the carnival to ride the rides. She wants LTU The Rocket. Eight rocket-shaped cars hang by chains from the outside edge of a large steel disk. A vertical axle through the center of the ride turns the disk, causing the cars to revolve in a circle. You've just finished taking physics, so you decide to figure out the speed of the cars while you wait. You estimate that the disk is...

2. A brav e 90 kg man, named Steve, agrees to give a Gravitron a test ride for the first time. The Gravitron has a diameter of 10 m. It is programed to spin faster and faster until it achieves ution in 15 s. Once it maintains this speed, the floor of the Gravitron lowers itself, s. Once it leaving the riders to hang in midair. raw a picture and an FBD of Steve as if you are looking at...

please ask that you clearly
go over what is different in each spot (top, bottom, and middle? I
don't understand the difference between the top and bottom, isnt
there just a normal force up and gravity down for both ? And isnt
there just a normal force up and gravity down in the middle too ??
Please help. And please make the force diagrams just so I can
really understand. (and please, please solve the whole problem I
really need...
