suppose you start a roller coaster car at the top of a hill with a height of 70 m and go around a loop- the- loop that has its bottom at ground level and has a radius of 15 m. If you weigh 70 kg. Calculate how heavy you will feel

a.at the top of the loop

b. at one of the sides of the loop

Remember, the weight you feel is the normal force.

A roller-coaster car may be represented by a block of mass 50.0 kg . The car is released from rest at a height h = 48.0 m above the ground and slides along a frictionless track. The car encounters a loop of radius R = 16.0 m at ground level, as shown. As you will learn in the course of this problem, the initial height 48.0 m is great enough so that the car never loses contact with the track....

Suppose a roller-coaster car is moving 31.3 [m/s] at the bottom of the first hill, and has an effective (rolling) friction coefficient 0.01 as it moves along the track. Predict how fast it would be at the top of the next hill, that is 30 [m] higher and 110 [m] farther along the track. This is on Earth, so use  g = 9.81 [N/kg]

A new roller coaster contains a loop-the-loop in which the car and rider are completely upside down. If the radius of the loop is 17.6 m, with what minimum speed must the car traverse the loop so that the rider does not fall out while upside down at the top? Assume the rider is not strapped to the car. (Give answer to the nearest 0.1 m/s)

The picture above shows the launch and first hills of a roller coaster. The cars are launched with some initial velocity, vi, go down a hill of height h1 = 4.13 m and over the first peak with height h2 = 7.69 m above the lowest point on the track. The shape of the first peak is a circle with a radius of R = 5.01 m. The ride is designed so that the riders feel weightless at the top...

Modern roller coasters have vertical loops like the one shown in the figure. 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. A) What is the speed of the roller coaster in m/s at the top of the loop if the radius of curvature there is 11 m and the...
