1. A student ties two rocks together with a lightweight 48.0 cm string. She takes a second string of length 30.0 cm and ties it to one of the rocks. She then swings the rocks around in a horizontal circle with that second, inner string. The inner rock has a mass of 84.0 g and the outer rock has a mass of 60.0 g. Her friend times the motion with a stopwatch as the rocks move together at a constant speed. They complete 10 revolutions in 13.8 s. Find the tension force exerted by each string as the rocks are moving at a constant speed. Top view 48.0 cm 30.0 cm mi m2
