Yes -- mgh = 1/2mv^2, where 'h' (33m) is the height difference between the top of the loop and the top of the coaster. Thank you!

Yes, that is how it's supposed to be pictured. Yes, you are right -- My teacher has demonstrated this question, thank you very much. So it would have been (as demonstrated), Ac = V^2/r r = V^2/ac r = V^2/3g A mistake. The angle is unnecessary. >.> Can you please demonstrate...

Homework Statement A) A roller coaster has a vertical drop but followed by a loop. The total vertical height of the drop is 66m. It starts as a steep slope at an angle of 75 degrees relative to the horizontal and then enters into a circular path of radius R. In order to stay below 4 times the...
