A 1500 kg roller coaster car starts from rest at a height of 23 m above the bottom of a 15 m diameter loop. If friction is negligible, determine the downward force of the rails on the car then the car is upside down at the top of the loop.

Step 1
First, we need to find the speed of the car at the top of the loop. We can use the conservation of mechanical energy principle for this. The initial potential energy (PE) at the top of the hill will be equal to the sum of the potential energy and kinetic energy Show more…

a 515 kg roller coaster is at the bottom of loop with radius of 10m it the speed at the bottom of the loop is 20m/s what is the force of the track pushing up ont the vehicle at this point?

Modern roller coasters have vertical loops. 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 at the top of the loop if the radius of curvature there is 15.0 m and the downward acceleration of the car is 1.50 g? B. How high above the top of the loop must the roller coaster start from rest, assuming negligible friction? C.If it actually starts 5.00 m higher than your answer to the previous part, how much energy did it lose to friction? Its mass is 1500 kg.
