Unformatted text preview: Question 1: Three uniform spheres of masses 4.90 kg, 6.70 kg, and 6.00 kg are placed at the corners of a right triangle as shown. Calculate the resultant gravitational force on the 4.90 kg object caused by the other two objects. Note: G = 6.67*10^(-11) Answer: ( 3.06 i , 2.7 j ) X 10^(-11) N Question 2: A meteorite of mass 2.80E8 kg orbits the Earth (mass=5.98E24 kg) such that its farthest from Earth is 5.10E9 m and its nearest to Earth is 2.30E8 m. Using G = 6.67*10^(-11) , find the following information. a.) The eccentricity of the meteorite's orbit: Answer: 0.914 b.) The meteorite's period: Answer: 4.33E7 s c.) The total potential energy of the meteorite-Earth system at aphelion: Answer:-2.19E13 J Question #3: The following information may be useful: Mass of a Proton 1.67E-27 kg Radius of a Proton 1.5E-18 m Velocity of Light 2.998E8 m/s Gravitational Force 6.67E-11 Assume that protons could be tightly packed into a spherical ball. What would the radius of such a ball be that would require the escape velocity would be equal to Assume that protons could be tightly packed into a spherical ball....
