When the ignition is first turned on a click noise is heard from under the hood of a vehicle equipped with etc. technician a says that this is the normal operation of the etc self-test. technician b says that the tac motor should not move unless the engine is running. which technician is correct?

Technician A

Explanation:

As soon as the system gets battery voltage, after ignition is turned, the efi computer makes a self-test of all the actuators and sensors, included the ETC.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
