2. We can use a simple model which uses ourunderstanding of uniform circular motion toestimate the largest possible rotational speed of aplanet around its own axis. For a planet of mass Mand radius R our model assumes that the planet"falls apart" when the loose rocks on the surface atthe equator are no longer sitting on the surfacebecause they leave the surface. A loose rock of massm is shown on the equator in the drawing.MmRС.Now return to the 'slowly' rotating planet (wherethe loose rocks are not flying off the surface) and consider aloose rock that is not on the equator, but at some higherlatitude, 0 (as shown). Do you need forces besides gravity andthe normal force to make this situation possible? Justify youranswer (you just need to justify whether you need anotherforce but not what that other force might be if it is needed).

35- A solid sphere of mass m and radius r can rotate without slipping along the path shown in the figure. At the height h where the sphere will start its motion from rest, the lowest part of the sphere is higher than the lowest part of the circular part of the road with radius R (R = 5r). What should be the minimum height (h) of the point where the sphere will start to move in order for the sphere to fully circle this circular path?

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.
