Question

What is throwing me off is that the acceleration is increasing, butdoes that not mean its positive since it going downward. Samewiith the velocity?

Since the length of v is directly proportionalto the length of Delta r , the vector connectingeach dot to the next could represent velocity vectors as well asposition vectors, as shown in the figure here below .Indicate whether the velocity and acceleration of the ball are,respectively, positive (upward), negative, or zero. Use P, N,and Z for positive (upward), negative, andzero, respectively. Separate the letters for velocity andacceleration with a comma. What is throwing me off is that the acceleration is increasing, butdoes that not mean its positive since it going downward. Samewiith the velocity?

Explanation / Answer

I can't see the figure, but if the acceleration is increasing inthe negative direction, then -if the velocity is initially in the positive direction it willdecrease and eventually change directions then increase again -if the velocity is initially in the negative direction it willincrease
