6 7 3 5 11 TO What is your answer? Question 2 Why is this your answer? Speed (m/s) 1949 92-10 60 70 00 90 100 Which is the correct answer? Which describes the difference in the motion of the object during the first 50 seconds of travel and between 50 and 75 seconds of travel? Why is this the correct answer? A. In the first 50 seconds the object's speed was increasing. Between 50 and 75 seconds the object was slowing down. B. In the first 50 seconds the objectwas traveling ata constant speed. Between 50 and 75 seconds the object was slowing down C. In the first 50 seconds the objectwas moving at a constant speed. Between 50 and 75 seconds the object's speed was increasing. D. In the first 50 seconds the object's speed was increasing. And between 50 and 75 seconds the object was traveling at a constant speed.

Answer 1

The motion of the object varies as indicated by changes in speed or acceleration. However, without numerical values or a graph, the exact nature of the change cannot be determined. The available options offer a generic understanding of motion in terms of acceleration (increase or decrease in speed) and constant speed.

Step-by-step explanation:

To determine the difference in motion of the object during the first 50 seconds of travel and between 50 and 75 seconds of travel, we analyze the speed of the object. If the object's speed was increasing initially, we would expect a positive acceleration during that period. Conversely, if the object's speed was constant, the acceleration would be zero. Then, between 50 and 75 seconds, if the object was slowing down, it would have a negative acceleration. If its speed remained unchanged, it would again have zero acceleration.

Given the options:

• A suggests an initial increase in speed followed by a deceleration.
• B proposes initial constant speed and then a deceleration.
• C offers initial constant speed and then an acceleration.
• D implies initial acceleration and subsequent constant speed.

Without specific numerical values or a graph depicting speed over time, it is impossible to ascertain the motion precisely. However, based on the general descriptions in the options, one can select between constant speed and acceleration or deceleration phases as they reflect general motion trends. If you have additional information such as a graph or numerical data points, these selections can be further refined.

Answer 2

As shown in the figure :

Which describes the difference in the motion of the object during the first 50 seconds of travel and between 50 and 75 seconds of travel?

So, in the first 50 seconds , as the time increase the speed increase as shown a line going up until he reached to time = 50

From 50 to 75 , is a constant speed with the value at the time = 50

so, the answer is option D.
