Hello everyone, i need help with these 2 question from physics. Im a year 11 physics student. Joey and Caitlin hang from two ends of a wire, looped through an ideal pulley. Joey has a mass of 75.0Kg, whilst Caitlin weighs 637N. a) calculate the tension of the wire? b) If Caitlin is not able to reach out and touch anything, is she able to change the motion of the system? Why?
