Suppose that the Sun runs out of nuclear fuel and suddenly collapses to form a white dwarf star. The size shrinks and became as big as earth. Assuming that there is no loss in mass and it maintained to be a solid sphere, what would be the little white dwarf star's rotation period. The present rotation of the sun is about 25 days. Earth's radius = 6.37x10^6 Sun's radius = 6.96x10^8

In this problem you will measure the gravitational constant in a series of “observational experiments,” making use of Newton’s law of gravitation and second law of motion as well as Kepler’s third law of planetary motion a)Since measuring the centripetal acceleration of an orbiting body is rather difficult, an alternative approach is to use the body’s rotational period instead. Enter an expression for the gravitational constant, in terms of the distance between Earth and the moon, RME, Earth’s mass,ME, and the moon’s period of rotation around Earth, T. b)Using the expression you entered in part (b) and taking the rotational period of the moon to be T = 27.1 days, what value would Newton have calculated for the gravitation constant, in units of N⋅m2/kg2? Take ME = 5.95×1024 kg and RME = 3.86×108 m. c) Suppose a rocket is launched as described in part (d) with an initial speed of vi = 494 m/s and attains a peak altitude of H = 12.7 km above the surface of Earth.

Problem 1: The figure shows a small sphere of mass m a distance D from the edge of a uniform rod of length L and mass M placed perpendicularly to the rod. The left edge of the rod is placed at the origin of an xy coordinate system. The x-direction points to the right, and the y-direction points up in the figure shown.The rod has a mass of 6.1 kg and the small sphere's mass is half the mass of the rod. The distance D = 1.4 m and the rod has a length of 1.4 m. What is the magnitude of the gravitational force, in newtons, of the ball?
