Estimate the average velocity vave of the car during the first 18 seconds. use the midpoint rule with n = 3. (round your answer to the nearest whole number.)
Accepted Solution
A:
v_ave=1/12int (t=0 to t=12) v(t) dt Using midpoint rule with n=3, we shall have: 12/3(v(2)+v(6)+v(10)) =4(20+50+66) =544 km-s/h hence: v_ave=(544 km-s/h)/(12 sec) =45 km/h (to the nearest whole number)
