Q1:

The graph shown be|0w is the velocity, in cm/sec, of an object moving along the xaxis between times t = O and t = 5 seconds. Positive velocity indicates motion to the right. u( I) (a) At time t = 5, where is the object in relation to its starting position? 5 The object is left of its starting position. C The object is right of its starting position. a The object is at its starting position. (b) At time t = 3, how far is the object from its starting position? cm (c) How far has the object traveled between t = 0 and t = 5? cm 20 Use the table given below and n = 4 to estimate f(x) dx .

Because the data is not monotone (only increasing or only decreasing), you should sketch a possible graph and draw the rectangles to ensure you are using the appropriate values for a lower estimate and an upper estimate. 20 f ( x ) dx lower estimate upper estimate
