3.) an engineer is designing the runway for an airport. of the planes that will use the airport,
the lowest acceleration rate is likely to be 3 m/s2. the takeoff speed for this plane will be 65
m/s. assuming this minimum acceleration, what is the minimum allowed length for the
runway?

704

Explanation:Vi = 0 m/s

vf = 65 m/s

a = 3 m/s2

d = ??

vf2 = vi2 + 2*a*d

(65 m/s)2 = (0 m/s)2 + 2*(3 m/s2)*d

4225 m2/s2 = (0 m/s)2 + (6 m/s2)*d

(4225 m 2/m2)/(6 m/s2) = d

d = 704 m

car a and b are moving in opposite directions

plz mark.me the brainliest i rlly need this kind of yours in exchange

answer: the direction of the wind is expressed as the direction from which the wind is blowing. for example, easterly winds blow from east to west, while westerly winds blow from west to east.
