Question:
- A roller coaster car (RC) of mass m = 1200 kg (includes passengers) is to be thrust into motion from a height H with a speed of vo = 2 m/s. It is to come down the track and complete a full circle along a vertical loop of radius R = 15m. Calculate the following:
- i) the least (minimum) speed the RC must have while traveling along the loop in order to prevent an accident (assuming frictionless conditions)?
- ii) how strong will the TRACK have to be at the bottom of the loop?
- iii) how strong the TRACK have to be at the top of the loop?
- iv) the energy transferred by gravity as the RC completes a semi-circle starting from the bottom of the loop to the top of the loop.
