Question

This question uses the following graph that shows the speed, v, versus time, t, for a light aircraft during take - off. 40 30 25 15- 20 6 7 910 Provide a series of estimates for the plane's acceleration at t- 3s by approximating the curve as a straight line between the following intervals: o t 3s and t 3s a. o t 3s and t 3s b b. Based on your estimates from part (a), estimate the acceleration of the aircraft at t-3s ec. Estimate the distance in metres covered by the aircraft during the first 8 seconds of the flight, giving your answer to two significant figures d d. Find the limit of the expression tnd: as &x -o (Hint evaluate the expression for smaller and smaller values of 8x and use these to identify a trend )
