1. The problem statement, all variables and given/known data Find the velocity with which a symmetric body of radius "R" starts to roll up an inclined plane if it was rolling without slipping on a horizontal plane with velocity "v1" and reached the incline. Angle of inclination of plane with horizontal=θ Radius of gyration of the body=k 2. Relevant equations I am trying to use- Angular impulse=Change in angular momentum 3. The attempt at a solution Assumed that the normal force exerted by the incline is mgcosθ. The velocity to find is v2. I am taking Angular momentum about the center of mass but I cant calculate the external impulse any help, ideas are much appreciated!
