Question

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

Answer the following questions using the velocity and time graph above.

A. At what time(s) was the car stopped?

B. At what time(s) was the car maintaining a constant velocity?

C. At what time(s) did the car accelerate?

D. At what time(s) did the car have a negative velocity?

Answer 1

A: 0.7 -0.8 and 0hrs
B: 0.2 - 0.4 and 1.0 -1.1 hrs
C: 0-0.2 hrs and 0.8 - 1.0 hrs
D: 0.4 - 0.7 hrs

Answer 2

A).  Stopped . . . . . 0.7 to 0.8 hours (velocity is zero)

B).  Constant velocity . . . . . 0.2 to 0.4 hours, and 0.7 to 0.8 hours, and also 1.0 to 1.1 hours  (velocity doesn't change as time passes)

C-pos).  Positive acceleration . . . . . Zero to 0.2 hours, and 0.8 to 1.0 hours  (velocity gets bigger as time passes)

C-neg).  Negative acceleration . . . . . 0.4 to 0.7 hours  (velocity gets smaller as time passes)

D).  Negative velocity . . . . . Nowhere on this graph  (velocity less than zero)
