What is her acceleration? What is her speed at the bottom?
Okay, this is weird.
I spent three hours on this. I feel the mass of the competitor is missing.
I separated the two dimensions. Both have non-zero acceleration (because there is a net force that is diagonal to the ice).
I get these equations:
I can’t solve because I get 0=0 on both sides if I try to add the equations.
What am I supposed to do? Please, I have an exam soon.
