As a roller coaster car crosses the top of a 40.0-m-diameter loop-the-loop, it's apparent weight is 1.90 times its true weight. What is the car's speed at the top? (The apparent weight is the same as the force of the tracks on the car)
As a roller coaster car crosses the top of a 52.0-m-diameter loop-the-loop, it's apparent weight is 1.60 times its true weight. What is the car's speed at the top? (The apparent weight is the same as the force of the tracks on the car)
The normal force equals the magnitude of the gravitational force as a roller coaster car crosses the top of a 56-m-diameter loop-the-loop. Part A What is the car's speed at the top? Express your answer to two significant figures and include the appropriate units. vtop = 6.57 Incorrect; Try Again; 4 attempts remaining
A certain roller coaster design uses a vertical loop of radius 7.248 m. Assuming that the roller coaster remains on the track, what is the minimum speed of a car at the top of the loop? (HINT: In general, the centripetal force is the vector sum of the car's weight w and the normal force N exerted by the tracks. The value of N varies with the speed. The minimum value of N is zero, which occurs when the roller...
A roller coaster car is going over the top of a 12-m-radius circular rise. At the top of the hill, the passengers "feel light," with an apparent weight only 60% of their true weight. How fast is the coaster moving?
A roller coaster car is going over the top of a 16-m-radius circular rise. At the top of the hill, the passengers "feel light," with an apparent weight only 60% of their true weight. How fast is the coaster moving?
Part of a roller-coaster ride involves coasting down an incline and entering a loop 7.10 m in diameter. For safety considerations, the roller coaster's speed at the top of the loop must be such that the force of the seat on a rider is equal in magnitude to the rider's weight. From what height above the bottom of the loop must the roller coaster descend to satisfy this requirement? m 1 -11 points SerCP8 7.P.019. My Notes Ask Your Teacher...
The passengers in a roller coaster car feel 1.20 times heavier than their true weight as the car goes through a dip with a 28.0 m radius of curvature. What is the car's speed at the bottom of the dip?
URGENTTT The passengers in a roller coaster car feel 1.70 times heavier than their true weight as the car goes through a dip with a 24.0 m radius of curvature. What is the car's speed at the bottom of the dip?
4) When sitting in a roller coaster going through a vertical loop of radius of 8.5 meters, your "ap- parent' weight is the normal force provided by the seat, while your "true" weight is the gravitational force (which is unluckily unchangeable at mg) a) How fast must you be moving at the top of the vertical loop to achieve weightlessness (i.e., to have no apparent weight)? b) If moving at the same speed on the bottom of the vertical loop,...
