You are located in the continental u. s. on the first day of october. how will the position of the sun at noon be different two weeks later? a. it will have moved toward the north. b.it will have moved to a position higher in the sky. c.it will stay in the same position. d.it will have moved to a position closer to the horizon. e.it will have moved toward the west.

Aparticle's position is given by x = 3.00 - 9.00t + 3t2, in which x is in meters and t is in seconds. (a) what is its velocity at t = 1 s? (b) is it moving in the positive or negative direction of x just then? (c) what is its speed just then? (d) is the speed increasing or decreasing just then? (try answering the next two questions without further calculation.) (e) is there ever an instant when the velocity is zero? if so, give the time t; if not, answer "0". (f) is there a time after t = 3 s when the particle is moving in the negative direction of x? if so, give the time t; if not, answer "0".
