Question
Snow fell and then stopped for a time. When the snow began to fall again, it fell at a faster rate than it had initially. Assuming that none of the snow melted during the time indicated, which of the following graphs could model the total accumulation of snow versus time?
Hint:
Hint:
- When speed increases there is positive acceleration, when speed is constant, the acceleration is zero and when speed decreases the acceleration is negative
The correct answer is:
Explanation:
- We have given a snow fell and then stopped for time, and then began to fall again with faster rate.
- We have to plot the graph of acceleration with time
Step 1 of 1:
It starts with an increase in acceleration with time (indicating snow fall) until it reaches a time where acceleration becomes constant (no acceleration, which means no snow fall). This continued for a period of time. After a certain period of time, the acceleration increased rapidly (at a rate faster than the initial) over time
So, Option (A) is correct.

Note:
When we have an inequality with the symbols < or > , we use dotted lines to graph them. This is because we do not include the end point of the inequality.

The graph above shows the positions of Paul and Mark during a race. Paul and Mark each ran at a constant rate, and Mark was given a head start to shorten the distance he needed to run. Paul finished the race in 6 seconds, and Mark finished the race in 10 seconds. According to the graph, Mark was given a head start of how many yards?
