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...

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 16.1 m/s at the top of the incline, which is 37.1 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 1.69 g at the top of the hump and no...

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 car of mass 500. kg on a roller coaster ride is raised from
the ground (horizontal dotted line) to point A as shown in the
diagram above. When the car passes point A, its speed is 5.0 m/s,
and then it rolls freely through the rest of the ride with
negligible friction, passing points B, C, D and E. Note that point
D is the highest portion of a circular loop, and point E is the
lowest portion of...

Problem 1 You are designing a roller coaster, shown in the figure below. An empty car has a mass of 120 kg. The radius of the vertical loop in the track is 12.0 m and the bottom of the loop is 5.0 m above the ground. Assuming the roller coaster is frictionless, how high must the car initially climb above the ground (point A) such that the speed of the car is 25.0 m/s at the top of the loop...

A car in an amusement park roller coaster ride rolls without friction at the top of a hill. The car begins at a height h from the top of a hill. A the bottom, the car then goes through a vertical loop where the car is upside down at the loop\'s top. If the radius of the loop is 20.0m, what is the minimum height h such that the car moves around the loop without falling off the track at...
