An object starts from rest at point F and speeds up continuously as it moves around an oval. a. Choose a point about 1/8 th of the way around the oval from point F, and label it point G. Draw a vector to represent the velocity of the object at point G. b. Determine the change in velocity vector  between points F and G.

(**i would really appreciate if this was answered soon** ) which pair of quantities includes one quantity that increases as the other decreases during simple harmonic motion?

A2k pendulum has a speed of 1 m/s at a height of 1/2 meter

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".
