An outdoor chair is suspended from a tree by a single cable of length 1.5 m. The mass of the chair and the person sitting in it is a total of 85 kg. If someone pulls the chair through a horizontal distance of 80 cm and holds it there: a. What is the increase in the force exerted by the cable? b. How much sideways force must be exerted to hold the chair at that location?
