Answer:
D. Freezing?
Explanation:
Get water, put it in the freezer, turns into ice after a few hours.
The statement that describes the error in the work is that the distance must be converted to meters (m).
<h3>FORMULA FOR WORK:</h3>
Work can be calculated by using the following formula:
W = F × d
Where;
- W = work done
- F = force (N)
- d = distance (m)
According to this question, the force is given as 140N and the distance is given as 30cm. The force is calculated as follows:
F = 140N × 30cm = 4200J
This calculation is erroneous because the unit of distance should be converted from cm to meters.

As it is a position time graph
So, it's slope represents velocity
During last 15 seconds
it passes through (5,17) (20,2)
Slope = -15/15 = -1
So Velocity= -1 m/s
