The velocity graph of an accelerating car is shown. v (km/h) 60- 40 20 4 8 t (seconds) 12 (a) Estimate the average velocity $V_{ave}$ of the car during the first 12 seconds. Use the Midpoint Rule with $n = 3$. (Round your answer to the nearest whole number.) $V_{ave} = 27$ km/h (b) At what time $t$ was the instantaneous velocity equal to the average velocity? (Round your answer to one decimal place.) $t = 5.2$ s

Step 1

To estimate the average velocity using the Midpoint Rule, we need to divide the time interval into smaller subintervals and find the average velocity on each subinterval. Then, we take the average of these average velocities to get the overall average velocity. Show more…
