Solve this:
Q.23. Calculate average velocity in the given v-t graph.


(A) 29.5 m/s
(B) 32 m/s
(C) 30 m/s
(D) 15.5 m/s

Dear Student ,
Here in this case , from the given graph we can get the average velocity ,
Average velocity=Vavg=Area under the graph from time t1 to t2total time=4×5+12×20×5+24×5+12×10×2420-0=31020=15.5 m/s
So the correct option is D .
Regards
