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

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.
