Assignment:
Question 1. The figure above shows the velocity vectors corresponding to the upward motion of the power ball. Indicate whether its velocity and acceleration, respectively, are positive (upward), negative, or zero.
Use P, N, and Z for positive (upward), negative, and zero, respectively. Separate the letters for velocity and acceleration with a comma.
Question 2. Since the length of is directly proportional to the length of , the vector connecting each dot to the next could represent velocity vectors as well as position vectors, as shown in the figure above. 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, and zero, respectively. Separate the letters for velocity and acceleration with a comma.
