A car in an amusement park ride rolls without friction around a
track (Figure 1). The car starts from rest at point A at a height h
above the bottom of the loop. Treat the car as a particle.
Figure 1:
PART A:
What is the minimum value of h (in terms of R) such that the car
moves around the loop without falling off at the top (point B)?
PART B:
If the car starts at height h= 4.30...

90 m (15 points) A roller coaster ride at an amusement park lifts a car of mass 700 kg to point A at a height of 90 m above the lowest point on the track, as shown above. The car starts from rest at point A. rolls with negligible friction down the incline and follows the track around a loop of radius 20 m. Point B. the highest point on the loop, is at a height of 50 m above...

In a popular amusement park ride, a rotating cylinder of radius 3 m is set in rotation as in the figure. The floor then drops away, leaving the riders suspended against the wall in a vertical position. (i) What force keeps the rider from slipping down without a floor? (ii) What force acts as the centripetal force in this situation? (iii) How many forces are acting on the rider? Name all of them.

At an amusement park, a car of mass m rolls without friction around a track as shown. The car starts from rest at point A, a height h = 3R above the bottom of the loop (R is the radius of the loop). Treat the car as a point-like particle. (a) Draw the free body diagram for the car and find the car’s kinetic energy and normal force acting on the car at the top of the loop (point B)....

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...

An amusement park ride has a vertical cylinder with an inner radius of 4 m, which rotates about its vertical axis. Riders stand inside against the carpeted surface and rotate with the cylinder while it accelerates to its full angular velocity. At that point the floor drops away and friction between the riders and the cylinder prevents them from sliding downward. The coefficient of static friction between the riders and the cylinder is 0.91. What minimum angular velocity in radians/second...

PRACTICE ANOTHER The figure shows a photo of a swing ride at an amusement park. The structure consists of a horizontal, rotating, circular platform of diameter D from which seats of mass m are suspended at the end of massless chains of length d. When the system rotates at constant speed, the chains swing outward and make an angle θ with the vertical. Consider such a ride with the following parameters: D = 8.50 m, d = 2.50 m, m...

A certain ride at an amusement park consists of a hollow cylinder that can rotate at high speeds. The floor can then be dropped with the people staying pinned to the sides of the cylinder. Terry the Mighty Iguana climbs inside the cylinder and the ride operator turns it on. The cylinder has a radius of 6 meters and a coefficient of friction between the cylinder wall and the Terry is u=0.67 a. how much friction is required to keep...

The figure shows a photo of a swing ride at an amusement park. The structure consists of a horizontal, rotating, circular platform of diameter D from which seats of mass m are suspended at the end of massless chains of length d. When the system rotates at constant speed, the chains swing outward and make an angle with the vertical. Consider such a ride with the following parameters: D = 9.00 m, d = 2.50 m, m = 9.4 kg,...

90 m (15 points) A roller coaster ride at an amusement park lifts a car of mass 700 kg to point A at a height of 90 m above the lowest point on the track, as shown above. The car starts from rest at point A. rolls with negligible friction down the incline and follows the track around a loop of radius 20 m. Point B. the highest point on the loop, is at a height of 50 m above...
