Q1. You approximate that it took the balloon about t seconds to fall the length of the window and that the window is about y meters high. Assume the balloon started from rest. Approximately how high above the top of window was it released?

Q2. Stone with a mass of 0.800 {rm kg} is attached to one end of a string 0.900 {rm m} long. The string will break if its tension exceeds 65.0 {rm N}. The stone is whirled in a horizontal circle on a frictionless tabletop; the other end of the string remains fixed.
