unproctored Test. QuestionSheet DE Update : The position of a particle moving straight line measured from a fixed point O on the line at time t seconds is given by: s(t) = -5+2t+ >t meter. Recall that the average velocity of the particle over the time interval between t second and 7 seconds is given by: Ave(t) = s(t) - s(7) m/sec. t - 7 Note that Ave(t) is undefine at t = 7. (A) Compute the average velocity Ave(t) for the given values of t near to 7 second. Enter your answers round to five decimal places in the table below. 6. 6.99 6.999 6.9999 7 7.0001 7.001 7.01 7.1 Ave(t) Number Number Number Number NA Number Number Number Number (B) From the answers in (A), what value does the average velocity of the particle approaches as t approaches 7 from the left? As t -+ 7", Ave(t) approaches the value Number (C) From the answers in (A), what value does the average velocity of the particle approaches as t approaches 7 from the right? As t - 7+, Ave(t) approaches the value Number (D) Estimate the limit of the average velocity Ave(t) of the particle as t approaches 7. lim Ave(t) = Number (E) What do we call the limit of the average velocity Ave(t) of the particle approaches as t approaches 7?
