Below are the numerical values of velocity at specific times. a) using the numerical method calculate the average acceleration during the time between t-2 seconds and t-3 seconds: . 2, b) calculate the position atts3 sec. you should assume that x-3m when t 0 [i. e., m] 610m numerical data v(0 sec) -4.0 m/s v(1 sec) -2.0 m/s v(2 sec) 1.0 m/s v(3 sec) 5.0 m/s v(4 sec) 10.0 m/s

Engineers find a new metal that is stronger than steel but much lighter. this material is also significantly cheaper than what is currently used for most aircraft, available in large quantities, and easy to manufacture. the engineers are excited because this new material will lower the costs of buying and operating airplanes for companies. what is probably the best step for the engineers to make next?
