Question

An inventive child named Nick 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, he pulls on the loose end of the rope with such a force that the spring scale reads 250 N. His true weight is 320 N, and the chair weighs 160 N. His feet are not touching the ground. a)Draw one pair of diagrams showing the forces for nick and the chair considered as separate systems and another diagram for the child and the chair as one system. b)Show that the acceleration of the system is upward and find its magnitude. c) find the force the child exerts on the chair.
