1. The problem statement, all variables and given/known data An inventive child named Chris wants to reach an apple in a tree without climbing the tree. Sitting in a chair connected to a rope that passes over a frictionless pulley, Chris pulls on the loose end of the rope with such a force that the spring scale reads 237.5N. Chris' true weight is 376N, and the chair weighs 87N. The acceleration of gravity = 9.8 m/s^2 Here's a drawing of the problem. Pardon my bad paint skills. Here's my freebody diagrams 2. Relevant equations Chris: Fnet=ma N- Fg= ma Chair: Fnet= ma T- Fg= ma T-Fg/ m I assumed that the tension in the rope is equal to the amount on the spring scale. When I substitute tension, Fg and mass into the Chair equation, I get a= 16.95 m/s^2. Apparently, that is wrong...Can someone tell me where I messed up?
