At the same instant that a 0.50 kg ball is dropped from 25 m above earth, a second ball, with a mass of .25 kg, is thrown straight upward from earth's surface with an initial speed of 15 m/s.
they move along nearby lines and pass each other without colliding. at the end of the 2s:
a. what is the height above earth's surface of the center of mass of the two-ball system?
b: what is the velocity of the center of mass of the two-ball system?
c: what is the magnitude of the acceleration of the center of the mass of the two-ball system?

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?

Scientist have use computer models to create a series of maps that show how susceptible coastal cities in island countries are to the sea rising at different levels.the map shows that a 1 meter rise would swap cities all along the us eastern seaboard. a 6-meter sea level rise with sub merge a large part of florida. thermal expansion has already raise the oceans 10 to 20 centimeters the most likely cause,directly and indirectly, for such a rise in sea level is
