Question

Please Help!!!!!! What is the acceleration of a car between 2 and 5 seconds? Hint: Acceleration is a change in speed and direction.
A. 15 m/s2

B. 0 m/s2

C. 5 m/s2

D. 30 m/s 2

Answer 1

Answer : B.  0 m/s∧2

Now we know that velocity = distance/ time

And acceleration = velocity/time.

From the graph we see that at the time interval 2 secs,the distance travelled is 10 m. Hence the velocity(v1) =10/2 = 5m/s.

From the graph we see that at the time interval 5 secs,the distance travelled is 25 m. Hence the velocity (v2) =25/5 = 5m/s.

Now acceleceration between the time interval of 2 ad 5 secs is calculated as

(v1-v2)/t2-t1 = (5-5)/(5-2) = 0 m/s∧2

Answer 2

Answer:

B. 0 m/s 2
