Approximate the displacement of the object on this interval by subdividing the interval into the ndicated number of subintervals. Use the left endpoint of each subinterval to compute the height of the rectangle Help Me Solve This h View an Example v 1/(2t+ 3) (m/s) for Osts8, n-4 Textbook Vi The approximate displacement of the object is 1 m.

Explanation / Answer

N = 4
As total time is 8 seconds, so each interval is of 2 seconds

v=1/(2t+3)
at 0 sec, v= 1/3
at 2 sec, v= 1/7
at 4 sec, v= 1/11
at 6 sec, v= 1/15
Displacement= 2*( 1/3 + 1/7 + 1/11 + 1/15) = 2.89
