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 coaster is just about to leave the track.)
A boy of mass 60.6 kg is about to disembark from a canoe of mass 39.1 kg. The canoe is initially at rest, with the bow just touching the dock (see figure). The center of the canoe is 3.0 m behind the bow. As the boy moves forward 6.0 m to the bow, the canoe moves away from the dock. How far is the boy from the dock when he reaches the bow?

A boy of mass 61.3 kg is about to disembark from a canoe of mass 41.7 kg. The canoe is initially at rest, with the bow just touching the dock (see figure). The center of the canoe is 3.0 m behind the bow. As the boy moves forward 6.0 m to the bow, the canoe moves away from the dock. How far is the boy from the dock when he reaches the bow?
A student with mass 58.0 kg rides on a roller coaster with a vertical loop. At the top of the loop the track has a radius of 19.7 m and the roller coaster moves at speed of 21.9 m/s at the top. Determine the normal force from the seat on the student at the top of the loop. Give your answer in newtons (N) and with 3 significant figures.
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)
9. As a roller coaster car crosses the top of a 41.0-m-diameter loop-the-loop, it's apparent weight is 1.80 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) x 12.7 m's
3. A 500 kg roller coaster is at the bottom of a loop with a radius of 10m. If the speed at the bottom of the loop is 20m/s, what is the force of the track pushing up on the vehicle at this point?
3. A frictionless roller-coaster goes around a circular loop of radius 11 m. It enters the bottom of the loop going 32 m/s. Find the speed of the roller-coaster when it gets to the top of the loop 4. For the loop in the previous problem find the velocity of the roller-coaster as a function of height off the ground. Use that to find the centripetal acceleration as a function of height. Plot the centripetal acceleration as a function of...
In order for the mass traveling around a circular roller coaster loop to stay on the track at the top of the loop, what must the mass' minimum speed be at the top of the 10 m radius loop?
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 student with a mass of m=60kg rides a roller coaster with a loop with a radius of curvature of r=6.0meters. What is the minimum speed the roller coaster can maintain and still make it all the way around the loop? (Other answers for similar problems solve using the law of conservation of energy. However, we have not learned that in our course yet, and have only reviewed uniform circular motion. Is there another way to solve this equation? does...
