A75 kg man is standing at the earth's surface. (a) what is the approximate magnitude of the gravitational force on the man by the earth. give your answer in newtons. get the mass and radius of the earth from the inside back cover of your text. remember, enter only the number; don't try to enter the units. n (b) what is the approximate magnitude of the force of gravitation on the same man by the sun. you may approximate the distance from the sun to the man by the distance from the sun to the earth; get that distance, as well as the mass of the sun, from the inside back cover of your book. n (c) what is the approximate magnitude of the force of gravitation on the same man by the moon. you may approximate the distance from the moon to the man by the distance from the moon to the earth; get that distance, as well as the mass of the moon, from the inside back cover of your book. n

Aspring is used to stop a 50-kg package which is moving down a 20º incline. the spring has a constant k = 30 kn/m and is held by cables so that it is initially compressed 50 mm. knowing that the velocity of the package is 2 m/s when it is 8 m from the spring and neglecting friction, determine the maximum additional deformation of the spring in bringing the package to rest.
