Question

The arrows show the velocity when the ball is at the arrow's tail. Position 0 is at the top. Construct the vector ?v0 = v1?v-1 by graphically subtracting the corresponding arrows. This difference represents the average velocity change as the ball passes from point -1 to point 1 at the top of the circle. Plot ?v0 with its tail on the ball at position 0.

Determine which of the following statements are true; e.g., if the first and last are true and the others false, enter TFFFT.

1- As the ball passes position 6, ?v6 points towards the centre of the circle.

2-?v0 points in the same direction as v0.

3-The acceleration is always at right angles to the velocity.

4-The acceleration a0 points in the same direction as ?v0.

5-?v0 points towards the centre of the circle.
