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

Explanation:

Step1: Determine the direction of velocity

The object is moving from left - to - right, so the direction of velocity is rightward.

Step2: Analyze the acceleration from the oil - drop diagram

The spacing between the oil - drops is increasing. This indicates that the object is speeding up. Since it is moving rightward and speeding up, the acceleration is also rightward.

Answer:

a. rightward, rightward
