EXERCISE A particle with velocity Ü. = -2î +4h in meters per second at t = 0 undergoes a constant acceleration à of magnitude a = 3ms-2 at an angle 0 = 130° from the a o positive direction of the x axis. What is the particle's velocity Ŭ at t = 5s, in unit vector notation and as a magnitude and an angle?

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
