50 POINTS A graph of velocity versus time for an object shows a straight line with positive slope. What does that indicate about the acceleration of the object?

- the acceleration is changing
- the acceleration is zero
- the acceleration is constant and positive

The acceleration is constant and positive

Explanation:

The straight line indicates that the acceleration is constant, while the positive slope indicates that the line is positive.

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

0 = 0.40 / 0 = 0

= 0.20 = 9.80 ⁄2 =?

=0 , = = 0.20 =0.50 0 0.40 ⁄

=0−122 =0−12(9.80 ⁄2)(0.50)2 =1.2
