Neutron stars, such as the one at the center of the Crab Nebula, have about the same mass as our sun but a much smaller diameter. If you weigh 655 N on the earth, what would be your weight on the surface of a neutron star that has the same mass as our sun and a diameter of 23.0 KG ? Take the mass of the sun to be = 1.99×1030 , the gravitational constant to be = 6.67×10?11 , and the acceleration due to gravity at the earth's surface to be = 9.810
A basketball is thrown horizontally with an initial speed of 4.90 m/s. A straight line drawn from the release point to the landing point makes an angle ? = 27.0° with the horizontal. What was the release height
A bullet of mass 0.0022 kg initially moving at 503 m/s embeds itself in a large fixed piece of wood and travels 0.71 m before coming to rest. Assume that the acceleration of the bullet is constant.
