A huge spring launched a cart with passengers into a roller-coaster with a circular loop, which has a radius of 8.00 meters. The whole roller-coaster is frictionless. At the top of a circular loop, the cart is moving with a speed of 10.0 m/s. The total mass of the cart with the passengers is 450 kg. a. [5] With that speed, does the cart stay in contact with the roller-coaster at the top of the loop? b. [2] At the...

Consider a roller coaster with a single, circular loop of radius R. Assuming no friction and no external driving once the car reaches the top of the first hill, at what height must the car start in order to make it around the loop? Assume that the car wheels cannot grip the rails, so that if the normal force at the top drops to zero then the car will fall off the loop. Give your answer as a multiple of...

A marble rolls around with no friction in a circular loop that has a radius of 40 cm. At the bottom of the loop, the speed is 7 m/s. A. Calculate the marble's centripetal acceleration and the angular speed when the marble is at the bottom of the loop. B. Using conservation of energy, determine the speed of the marble at the top of the loop. C. Calculate the magnitude of the centripetal acceleration and the angular speed of the...
What is the speed, in m/s, of the roller coaster at the top of the loop if the radius of curvature there is 20.0 m and the downward acceleration of the car is 1.50 g?
Modern roller coasters have vertical loops like the one shown in the figure below. The radius of curvature is smaller at the top than on the sides so that the downward centripetal acceleration at the top will be greater than the acceleration due to gravity, keeping the passengers pressed firmly into their seats. What is the speed, in m/s, of the roller coaster at the top of the loop if the radius of curvature there is 20.0 m and the downward...

A roller coaster car is going over the top of a 15 m- radius circular rise. At the top of the hill, the passengers "feel light" with an apparant weight only 50% of their true weight. How fast is the roller coaster moving?

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...

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...

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...
