# Velocity and Acceleration - Position versus Time

Please give the solution and a step-by-step way to figure the answers out please. Learning is important.

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.

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

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

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

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

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
