Ascience student is riding on a flatcar of a train traveling along a straight horizontal track at a constant speed of 10.3 m/s. the student throws a ball along a path that she judges to make an initial angle of 50.7° with the horizontal and to be in line with the track. the student's professor, who is standing on the ground nearby, observes the ball to rise vertically. how high does the ball rise? (neglect air resistance.)

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}.
