The two objects in the figure are separated by 4 m, each have a mass of 5 kg, and are connected by a massless cable. They rotate about their common center of mass (2m from each) with a constant angular speed of ω0= 10 rad/s. After five seconds, what distance (arc length) has each mass travelled (if their angular speed is constant)? A) 10 m B) 20 m C) 40 m D) 50 m E) 100 m F) 200 m

Intro Physics I, Homework #7 See Walker Ch. 5, 6.1, 6.3, 7.1-7.2, 13.1 Submit to Google Classroom by 10 P.M., Monday, April 4 Remember to show all work and include units In Newton's late 17th century era, there were relatively accurate estimates, from terrestrial and astronomical observations and experiments, of the distance of the Earth to the Sun (dEs = 150 million 1. kilometers) and the circumference of the Earth (Cp = 40,000 kilometers [the meter was later defined during the late 18th century French revolution in relation to the size of the Earth]). Newton further estimated, likely based on the density of rocks, that the Earth was a solid sphere with a density about 6 times the density of water, which has density of pwater = 1 g/cm³.
