As a ball moves along a circular path, its speed is seen to increase. Its velocity is shown at a given point along its circular trajectory in the figure, below. At the position shown, which of the following vectors indicates the possible direction of the net acceleration a of the ball. (The "x" indicates the center of the circle in each case.)

A ball attached to a string is moved at constant speed in a horizontal circular path. A target is located near the path of the ball as shown in the diagram. At which point along the ball's path should the string be released, if the ball is to hit the target? (A) $A$ (B) $B$ (C) $C$ (D) $D$
An object is moving in a clockwise direction around a circle at constant speed as shown in this diagram: Which vector below represents the direction of the acceleration vector when the object is located at point A on the circle?

A ball swings in a vertical circle at the end of a rope $1.50 \mathrm{~m}$ long. When the ball is $36.9^{\circ}$ past the lowest point and on its way up, its total acceleration is $(-22.5 \mathbf{i}+$ $20.2 \mathrm{j}) \mathrm{m} / \mathrm{s}^{2}$. At that instant, (a) sketch a vector diagram showing the components of this acceleration, (b) determine the magnitude of its radial acceleration, and (c) determine the speed and velocity of the ball.
