Readings at 12 second intervals. Estimate distance traveled Deltax= 12

t(s)0 12 24 36 48 60 v(ft/s)32 28 24 22 24 28

1. estimate distance using the velocities in the beginning of the time intervals:

=156 = 12(28+24+22+24+0)=L6 This is correct

2. give another estimate at the end of the time intervals.

I did 12(32+28+24+22+24+28) = 1896 =R6 Which is wrong

PART B)

Are your estimates in parts (a) and (b) upper and lower estimates? Explain.

a (b) is a lower estimate and (a) is an upper estimate sincevis a decreasing function oft.

b (a) is a lower estimate and (b) is an upper estimate sincevis an increasing function oft.

c. (a) and (b) are neither lower nor upper estimates sincevis neither an increasing nor decreasing function oft

I chose b but it's wrong. But I believe it is choice c since the intervals are an irregular curve
