Assignment:
Use the data for all these questions on position versus time. The graph points are at 8 meters t=0 seconds. -4 meters at 1 second, -8 meters at 2 seconds, -4 meters at 3 seconds, 0 meters at 4 seconds and 28 meters at 5 seconds.
Question 1. What is the change in position of the object during the time from 1 second to 2 seconds?
a) -8 meters
b) -4 meters
c) 0 meters
d) 4 meters
e) 8 meters
Question 2. What is the average velocity of the object between 0 and 2 seconds.
a) -8 meters/s
b) -4 meters/s
c) 0 meters/s
d) 4 meters/s
e) 8 meters/s
Question 3. What was the avergae velocity of the object between t=1 and t=5 seconds?
a) -4 meters/s
b) 6 meters/s
c) 0 meters/s
d) 4 meters/s
e) 8 meters/s
Question 4. What was the acceleration of the object during the time shown?
a) -4 meters/s^2
b) 4 meters/s^2
c) -8 meters/s^2
d) 8 meters/s^2
e) 0 meters/s^2
Question 5. What was the intial velocity of the object at t=0 seconds? Hint: calculate the velocity at different times, then make a graph of velocity versus time.
a) -16 meters/s
b) -12 meters/s
c) -4 meters/s
d) 0 meters/s
e) 4 meters/s
