Question

2. A test plane fles in a straight line with positive velocity vt) in miles per minute at time tminutes, where vis a differentiable function of t. Selected values of v(t) are shown in the table below. Use a midpoint Riemann sum with four subintervals of equal length to approximate J, (t)dt, then using correct units, explain the meaning of the approximation. 0 5 10 15 20 25 30 35 40 (minutes) v(t) (miles per minute) 7.0 9.2 9.5 7.0 4.5 2.4 2.4 4.3 7.3
