Question

QUESTION 18 A car accelerates at 5 m/s2 for 8 seconds. The direction of its acceleration is due east. If its initial velocity was 7 m/s, also due east, what is its average speed during this time interval? Round your answer to the two decimals. QUESTION 19 A car accelerates at 7 m/s2 for 2 seconds. The direction of its acceleration is due east (east - positive direction). If its initial velocity was 47 m/s, due west, what is its final velocity? Round your answe to the nearest meter per second. QUESTION 20 A car accelerates at 5 m/s2 due east (east- positive direction). If its initial velocity was 6 m/s, also due east, what how long before it reaches final speed of 31 m/s? Round your answer to two decimals QUESTION 21 A car accelerates due east for 9 seconds. If its initial velocity was 8 m/s and its final speed was 29 m/s both due east, what was its acceleration? Round your answer to the two decimals. QUESTION 22 A car accelerates at 6 m/s2 for 4 seconds. The direction of its acceleration is due east (east- positive direction). If its final velocity is 30 m/s, also due east, what is its initial velocity? Round your answer to the nearest meter per second. Choose positive direction due east
