ok i this question has been asked but whoever asked it did not show work therefore did not have it answered so here we go my attempt!! 1. The problem statement, all variables and given/known data Show that on a roller coaster with a circular vertical loop the difference in your apparent weight at the top of the loop and the bottom of the loop is 6 g's that is 6 times your weight. ignore friction. h = height of start of roller coaster R = loop's radius 2. Relevant equations PE = KE a = v^2/R 3. The attempt at a solution at the top of loop: mgh = mg2R + .5mv^2 solved for velocity v^2 = 2g(h-2R) centripital acceleration is a = v^2/R ---> a = 2g(h-2R)/R also i knew from another problem that minimum h had to be 2.5R to be able to go through the whole loop and stay on track so... a = g? haha yeah i am lost i have no idea what to do. I am trying to teach this course to myself and i am really struggling without a teacher. Please help?
