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 194 N. Chris’s true weight is 293 N, and the chair weighs 76 N.
1. Discover the magnitude of the acceleration of the system. The acceleration due to gravity is g = 9.8 m/s2
Answer in units of m/s2.
2. Discover the magnitude of the force Chris exerts on the chair.
Answer in units of N.
