I dont remember the question verbatim, but here is all the info 1. The problem statement, all variables and given/known data There is a mass attached to a rope which is attached to a pole. It is set to rotate on a horizontal surface (basic circular motion scenario). There is no kinetic friction along the table, but there is air friction. The magnitude of air friction is related to velocity with the equation .2v. m=3 kg r=2 m v(initial)=10 m/s What is the centripetal acceleration after 5 s. 2. Relevant equations F=ma=m(v^2/r) 3. The attempt at a solution i know you gotta integrate the air friction function over the 5 s interval, but i cant express it in terms of t. I am completely lost, please help. I know I got it wrong, but i really wanna know how to do it. Thanks!
