Arailroad freight car with mass 30,000 kg collides is moving in the +x direction at 2.00 m/s when it collides with a stationary caboose car. the two cars couple together, and move down the track at vf. during the collision, 50.0% of the original kinetic energy is lost to thermal energy, sound, vibrations, and so on. find the mass of the caboose in kg.

Asatellite that goes around the earth once every 24 hours iscalled a geosynchronous satellite. if a geosynchronoussatellite is in an equatorial orbit, its position appearsstationary with respect to a ground station, and it is known as ageostationary satellite find the radius rof the orbit of a geosynchronous satellite that circles the earth.(note that ris measured from the center of the earth, not the surface.) you mayuse the following constants: the universal gravitational constant g is 6.67 \times 10^{-11}\; {\rm n \; m^2 / kg^2}. the mass of the earth is 5.98 \times 10^{24}\; {\rm kg}. the radius of the earth is 6.38 \times 10^{6}\; {\rm m}.
