Question

mission kc5: oil drop representations
an object is moving from right to left. its motion is represented by the oil drop diagram at the right. this object has a ________ velocity and a ________ acceleration.
a. rightward, zero
b. leftward, zero
c. rightward, rightward
d. leftward, leftward
e. rightward, leftward
f. leftward, rightward
g. none of these

Explanation:

Step1: Determine velocity direction

The object moves from right - to left, so velocity is leftward.

Step2: Determine acceleration direction

The oil - drop spacing decreases, meaning the object is slowing down. Slowing down while moving leftward implies a rightward acceleration.

Answer:

f. leftward, rightward
