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

A 686 N park ranger uses a basket and a rope-pulley system to transport an injured sea turtle up to a plateau, as shown in the figure. The sea turtle and basket together have a mass of 50.0 kg. The ranger holds firmly onto the rope and walks away from the cliff, speeding up at a steady rate of 0.300 m/2 2. He thereby causes the basket (and the turtle) to accelerate straight upwards at the same rate. Assume that the rope has negligible weight and that the pulley is ideal, having no friction in its bearing. Also assume that as the ranger trudges along, his feet do not slip on the ground. +x 26.
