Acup sits on a table. due to its position, the potential energy of the cup is 3.00 joules. ignoring frictional effects, if the cup falls off the table, how much kinetic energy will it have when it is halfway to the floor? 3.00 j 1.50 j 0.00 j cannot be determined without knowing the mass and the height of the cups

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}.
