Question
A race car moves such that its position fits the relationship x-(4.5 m/s)t + (0.80 m/s³³ where x is measured in meters and in seconds. (a) A plot of the car's position versus time is which of the following? برسا 100- O x(m) 90 80 70 60 30 30 20 10 O x(m) 240 220 200 180 160 140 1201 100 80 60 200 180 160 140 120 EL 100 80 40 20 t(s) 40 1.00 2.00 20 t(s) 3.00 4.00 5.00 6.00 1.00 2.00 3.00 4.00 5.00 x(m) 6.00 30 25 20 15 10 5 x(m) t(s) 1.00 2.00 3.00 4.00 5.00 6.00 220 t(s) 1.00 2.00 3.00 4.00 5.00 6.00 (b) Determine the instantaneous velocity of the car at t-4.4 s, using time intervals of 0.40 s, 0.20 s, and 0.10 s. (In order to better see the limiting process keep at least three decimal places in your answer.) At-0.40 s m/s (Use the interval from t-4.20 sto 4.60 s.) At -0.20 s m/s (Use the interval from t-4.30 sto 4.50 s.) At - 0.10 s m/s (Use the interval from t-4.35 sto 4.45 s.) (c) Compare the average velocity during the first 4.4 s with the results of part (b). The average velocity of mys is -Select- the instantaneous velocity.
