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...

The mass of a roller-coaster, including its passengers, is 500.0 kg. The radius r 2 of the highest track (point B) in the figure is 40 m. Find the speed of the roller-coaster when the passengers feel weightless at the the top of the track. Weightless is the condition when the contact force between the coaster and the track is zero, that is, the normal force is zero. Use g = 10 m/s. 20 m/s 10V3 m/s 10 m/s 10v5...

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...

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...

Problem 1 A roller coaster cart has a mass of 200.0kg, which includes its passengers. The cart is pushed off its beginning position by a spring with a spring constant of k 150.ON/m that has been compressed by Ax 0.50m from its equilibrium length. Friction is negligible everywhere, except for a 2-meter-long rough patch on the initial slide (see the figure below), where the coefficient of kinetic friction is uk 0.4. (For the purposes of calculation involving friction, here you...

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 roller-coaster car has a mass of 660 kg when fully loaded with passengers. The car passes over a hill of radius 15 m, as shown. At the top of the hill, the car has a speed of 8.2 m/s. What is the force of the track on the car at the top of the hill?

A roller-coaster car has a mass of 498 kg when fully loaded with passengers. The path of the coaster from its initial point shown in the figure to point B involves only up-and- down motion (as seen by the riders), with no motion to the left or right. Assume the roller-coaster tracks at points and Bare parts of vertical circles of radius r1 = 10.0 m and r2 = 15.0 m, respectively. (a) If the vehicle has a speed of...
