1. The problem statement, all variables and given/known data 2. Relevant equations f=m*a V= Vg*cos θ 3. The attempt at a solution Is this solution correct. I did everything the same, but I did not use the 15 ft/s. Since An= (v^2/ρ) with V being the velocity in the t direction. The 15 ft/s according to me is only the component of V that is in the y direction of a normall x-y plane. So to get the velocity in the tangential direction of the path, so the full V. You need to do 15 ft/s / cos θ? That they use Vg as V in the equation for An is wrong?
