A meteoroid is moving towards a planet. It has mass m= 0.18x10⁹ kg and speed v1 = 5.9x10⁷ m/s at distance R1 = 2.9x10⁷ m from the center of the planet. The radius of the planet is R = 0.22x10⁷ m. The mass of the planet is M = 2.4x10²⁵ kg. There is no air around the planet.
Calculate the speed of the meteoroid just prior to the instant when it hits the surface of the planet, in meters per second.

The astronauts on the space shuttle flights experienced an acceleration of 29 m/s2 (about 3 "g's") during lift-off. what upward force must the astronaut's seat apply to the astronaut in order to cause this acceleration? assume the astronaut's mass is 70 kg, and compute this force when the acceleration is near the earth's surface so their weight equals latex: mg m g .
