An airplane starts from rest and accelerates at a constant rate of 3.00 m/s2 for 30.0 s before leaving the ground. a. how far did it move? b. how fast was it going when it took off?

The formula we can use in this case is:

d = v0t + 0.5 at^2

v = at + v0

where,

d = distance travelled

v0 = initial velocity = 0 since at rest

t = time travelled

a = acceleration

v = final velocity when it took off

a. d = 0 + 0.5 * 3 * 30^2

d = 1350 m

b. v = 3 * 30 + 0

v = 90 m/s

Explanation:

The civil service is a collective term for a sector of government composed mainly of career bureaucrats hired on professional merit rather than appointed or elected, whose institutional tenure typically survives transitions of political leadership
