1. The problem statement, all variables and given/known data Jarek is motoring along when he spots Chris and Michelle thumbing a ride back to Winnipeg. He hitches them up to two ropes and accelerates westward towards Winnipeg, He pulls with a constant force on a rope which slopes down 30 degrees to Chris's belt. A second rope attached to Chris' belt pulls Michelle's belt. Assume there is no friction force between the level snow-covered road and their skis and that the only motion is their acceleration west. Calculate the tension in the rope joining Michelle and Chris. Mass of Chris = 70Kg; mass of Michelle = 50Kg; mass of Jarek = 60Kg; mass of motorcycle = 100Kg. 2. Relevant equations Given: Chris= 70Kg Michelle= 50Kg Jarek= 60Kg + 100Kg; 160Kg a= constant Fnet = mg 3. The attempt at a solution Fnet = mg = (50Kg)(9.8N/Kg) = 490N Fnet = Ff + Fa Ff = 0 Fa = 490N [W] It seems a little too simple, can someone please check over my work? Thanks, I really appreciate it.
