Let's design a roller coaster. It should
consist of a long ramp leading into a loop. The loop should have a
radius r of 7.4 m. The cars have a mass M of 348 kg. Assuming that
friction can be neglected here, what should be the minimum height h
of the ramp (in m) with respect to the bottom of the loop so that
the cars don't fall off the track at the top of the loop?

4. A roller-coaster with a loop-the-loop is designed so that the cars are a very strong spring that is compressed by the cars and then the cars are rele from rest for the launch. The track is frictionless except for a 12m long rough section before the loop. The coefficients of static and kinetic friction between the cars and the track in the rough section are 0.8 and 0.12, respectively. The loop has a radius of curvature of 18m. What...

A roller coaster starts from rest at a height h at the left side of a loop-the-loop, as shown in the figure. It is not attached to the track in anyway, and there is no friction from the track or from air resistance. If the radius of the loop is R = 6.0 m, what is the minimum height h for which the roller coaster will not fall off the track at the top of the loop?...

Problem 1: Looping. The looping of a roller coaster has the radius R. The roller coaster starts at rest in height H over the deepest point of the looping (as shown in the figure). Neglect friction and consider the roller coaster as a mass point of mass m. Q.1) Express the total energy of the body. The reference point for the potential energy is at the center of the loop. Q.2) Find the speed of the body at the top...

A roller-coaster car shown in the figure on the right is released from rest from a height h and then moves freely with negligible friction. The roller-coaster track includes a circular loop of radius R in a vertical plane. a. First suppose the car barely makes it around the loop; at the top of the loop, the riders are upside down and feel weightless. Find the required height h of the release point above the bottom of the loop in...

When a roller coaster went upside down at the top of a loop with a radius 8.0m, a speed of 11.2m/s was required to make the coaster feel safe. A. Assuming that air resistance and friction are negligible , what speed will the roller coaster have when it is right-side up at the bottom of the loop? B. The roller coaster begins its trip by being pulled up the lift hill by a chain lift and dropped after it reaches...

A certain roller coaster design uses a vertical loop of radius 7.248 m. Assuming that the roller coaster remains on the track, what is the minimum speed of a car at the top of the loop? (HINT: In general, the centripetal force is the vector sum of the car's weight w and the normal force N exerted by the tracks. The value of N varies with the speed. The minimum value of N is zero, which occurs when the roller...

PLEASE ANSWER CORRECTLY THE CORRECT ANSWER IS 46
A roller coaster cart starts at the top of a quarter circular
hill (no friction) of some radius at a speed of 11.8
m/s. At the bottom of the hill it encounters a
horizontal surface with friction and the coefficient of kinetic
friction is 0.55. It travels over that horizontal surface for 8
meters and encounters a frictionless loop with a radius of 23
meters. If it is to just barely make...

You are designing a new roller-coaster. The main feature of this particular design is to be a vertical circular loop-the-loop where riders will feel like they are being squished into their seats even when they are in fact upside-down (at the top of the loop). The coaster start at rest a height of 80m above the ground, speeds up as it descends to ground level, and then enters the loop which has a radius of 20m. Suppose a rider is...

The force of contact between the bottoms of some roller-coaster riders and their seats vanishes just at the moment the are at the top of a loop, with radius 18.0m. What is the speed of the roller coaster at the bottom of this loop if there is no friction with the track?
