A mass m1 of 1750 kg is fixed in place on a frictionless surface at a distance L

Question

A mass m1 of 1750 kg is fixed in place on a frictionless surface at a distance L = 10.7 mm from a second mass m2 of 189 kg. Mass m2 is free to move. The surface is slowly tilted. At what angle of inclination will the second mass begin to slide down the plane? The acceleration of gravity is 9.8 m/s2 and the value of the universal gravitational constant is 6.67259 times 10-11 N middot m2/kg2. Answer in units of degree A satellite moves in a circular orbit around the Earth at a speed of 5.9 km/s. Determine the satellite's altitude above the surface of the Earth. Assume the Earth is a homogeneous sphere of radius 6370 km and mass 5.98 times 1024 kg. The value of the universal gravitational constant is 6.67259 times 10-11 N middot m2/kg2. Answer in units of km Tom has a mass of 74.1 kg and Sally has a mass of 51.8 kg. Tom and Sally are standing 25.4 m apart on a massless dance floor. Sally looks up and she sees Tom. She feels an attraction. If the attraction is gravitation, find its magnitude. Assume both can be replaced by spherical masses and that the gravitational constant is 6.67259 times 10-11 N middot m2/kg2. Answer in units of N
