Question

PLEASE HELP ASAP

Describe the motion of an object between 0 and 8 seconds which is represented in the graph above. Give the number of seconds for each type of movement.


(HINT: There are four changes of its motion. USE the word bank below to help.)


4 seconds 2 seconds 1 second 1 second

increased velocity constant velocity constant velocity decreased velocity

Answer 1

The motion of the object between 0 and 8 seconds, as represented by the graph above, can be broken down into four segments:

For the first 4 seconds, the object experiences an increased velocity. This means that the object is accelerating downwards due to the force of gravity. During this time, the velocity increases at a constant rate of 9.8 m/s^2.

Between 4 and 6 seconds, the object experiences a constant velocity. This means that the object continues to fall with a steady speed, without any further increase in its velocity.

Between 6 and 7 seconds, the object again experiences a constant velocity. This means that the object continues to fall with the same steady speed as before.

Finally, between 7 and 8 seconds, the object experiences a decreased velocity. This means that the object is decelerating, or slowing down, as it approaches the ground. This could be due to air resistance or other factors.

So, to summarize, the motion of the object between 0 and 8 seconds is characterized by an initial increase in velocity for 4 seconds, followed by two periods of constant velocity for 2 seconds and 1 second respectively, and finally a decrease in velocity for 1 second.
