What is the kinetic energy of a car with a mass of 1000 kg traveling at a speed of 20 meters second." 0 200.000 Joules O 200.000 Newtons O 200.000 miles/hour O 200.000 was What is the potential energy of a rock with a mass of 3 kg that is 10 feet​

The sun’s mass is 2.0×10^ 30 kg, its radius is 7.0×10 5 km, and it has a rotational period of approximately 28 days. if the sun should collapse into a white dwarf of radius 3.5×10 3 km, what would its period be if no mass were ejected and a sphere of uniform density can model the sun both before and after?
