1. A driver of a car steps on the brakes. Let v(t) denote its speed in feet per second, t
seconds after the brakes are applied. If v(0) = 105, v(1) = 75, v(2) = 20 and v(2.5) = 0,
then give an underestimate and an overestimate for how far the car travels as it comes to
a stop
2. Using the right-hand rule with 5 evenly-spaced rectangles set up (but do not compute)
the Riemann sum for R2
0e−x2dx. Sketch a graph. showing the rectangles.
3. Suppose R9
3h(x)dx = 0. What can you conclude about h(x) ?
