When a roller coaster went upside down at the top of a loop with a radius 8.0m, a speed of 11.2m/s was required to make the coaster feel safe. A. Assuming that air resistance and friction are negligible , what speed will the roller coaster have when it is right-side up at the bottom of the loop? B. The roller coaster begins its trip by being pulled up the lift hill by a chain lift and dropped after it reaches...

You are riding the new rollercoaster Fizzix Phun at your local amusement park. The technician with a mass of 100kg clears your car for 'takeoff'. The rollercoaster car full of people with a mass of 1000 kg is pulled up the initial hill by a lift device. The maintenance stairs up to the top of the hill consists of 11 flights of 30 stairs each wherein a single stair is 10cm high. The drop down the first hill is terrifyingly...
