Alight, rigid rod is 63.3 cm long. its top end is pivoted on a frictionless horizontal axle. the rod hangs straight down at rest with a small, massive ball attached to its bottom end. you strike the ball, suddenly giving it a horizontal velocity so that it swings around in a full circle. what minimum speed at the bottom is required to make the ball go over the top of the circle?

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".
