If there is no rail, the skier must have enough speed for to hold him against the loop. If he tries to attempt the loop from less then 37.5m, he would approach the top half of the loop and just fall to the ground?

thanks for your reply, yes I tried to calculate it again with the ## mg(2r) ## term and got 37.5 m. This refers to (b) when the skier has no securing system. But I'm still not sure about how to solve (a) considering the rail.

I didn't consider the velocity at the bottom, but the minimal velocity. If I understood correctly.. Oh sorry I will post my way now. Let me know if images are fine or maybe I should write the equations here aswell. And That was my third assumption:

Hey, thanks for reaponding. I just assumed that the calculation should be different if they asked 2 different things..

I have an assignment in physics and I can't understand the difference between the 2 questions. That's the question A skier with mass m=70 kg stands on a ramp of height h. At the foot of the ramp, there is a loop with a radius of r=15 m. When entering the ramp, the speed is v1=0 m/s. a) For...
