A car traveling 29 mi/h accelerates uniformly for 8.5 s, covering 471 ft in this time. What was its acceleration? Round your answer to the nearest 100th place. Answer in units of ft/s.

Explanation:

We know that :

u = 29 mph = 12.96 m/s

S = 471 ft = 143.5 m

t = 8.5 sec

143.5 = 12.96 * 8.5 + 1/2 * a * 72.25

a = 66.68 / 72.25

a (Acceleration) = 0.92 m/sec^2

= 3.01 ft/sec^2

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
