(Q) A girl is swinging back and forth on a swing suspended from a rope 10m long. At the lowest point of her swing she is 1m from the ground, and at the highest point she is 2m above the ground. What will be her maximum velocity? Would her maximum velocity be at the lowest point d = 1m above the ground? Is so v= d /t .... ??? Or is this related to her potentional and kinetic energy?
