A roller coaster begins at rest at the top of a 38 m hill. Find the velocity at a point 8 m above the bottom of the hill. Hint: PE at point 1 = (KE+PE) at point 2
Consider the roller coaster pictured. The coaster car (m= 1000 kg) starts from rest at (1) the top of the first hill at height H = 40 m. It then (2) drops, (3) goes over the second hill assume semicircular) of height L, and (4) around the loop of radius R, all frictionless. After finishing the loop (5), it encounteres frictional resistance u = 1 on the track at and (6) hits an armadillo (mA = 5 kg) at distance...

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 track is set up so that the coaster starts from rest, falls, and proceeds to go through a loop according to the picture. Ignore friction. The photogates can be used to determine the velocity of the cart. Using energy conservation, find the minimum height the cart must start from in order to complete the loop. Need some help working out these equation. Any help is really appreciated!! Track Car Photogate
A 2,494-kilogram roller coaster car starts at point A almost at rest. It first runs downhill and then is approaching a hill. At its top, the hill can be described by a circle with radius 9 m. Find the height required at point A, such that the normal force acting on the car in point B is 73% of the weight. Make sure to practise how to explain your work and also how to evaluate your result. Draw proper diagrams...
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...
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...
