QUESTION 10 A car accelerates at 6 m/s² for 5 seconds. The direction of its acceleration is due east (east = positive direction). If its initial velocity was 48 m/s, due west, what is its final velocity? Round your answer to the nearest meter per second. -18 m/s^2 QUESTION 11 A car accelerates at 3 m/s² due east (east = positive direction). If its initial velocity was 2 m/s, also due east, what how long before it reaches final speed of 24 m/s? Round your answer to two decimals. 7.33 seconds QUESTION 12 A car accelerates due east for 8 seconds. If its initial velocity was 5 m/s and its final speed was 20 m/s both due east, what was its acceleration? Round your answer to the two decimals. 1.88m/s^2 QUESTION 13 A car accelerates at 6 m/s2 for 2 seconds. The direction of its acceleration is due east (east = positive direction). If its final velocity is 28 m/s, also due east, what is its initial velocity? Round your answer to the nearest meter per second.
