What is the speed of the spools ground-touching point

Reference no: EM13500295

A spool whose inner core has a radius of 1.00 cm and whose end caps have a radius of 1.50 cm has a string tightly wound around the inner core. The spool is free to roll without slipping on a horizontal surface. If the string unwinds horizontally from the top of the core with a constant speed of 20.0 cm/s, what is the speed of the spools ground-touching point?
