The earth spins at a rate of over 1000 miles per hour. If this is the
case, you must move at this same rate in order to stay in contact with
the ground. Why then, when you jump up and let go of the ground,
does the wall not smack you in the side? If the wall did smack you,
which one would do the damage? (west, east, north)

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".

In addition to gravity, what is the other predominant force that affects the motion of a pendulum?
