A plane decelerates at a constant rate of 3.9 m/s [W]. If the plane's initial velocity was 24 m/s [E], how long does it take for the
plane to come to a complete stop?

t = 6.15 [s]

Explanation:

To solve this problem we must use the following equation of kinematics.

where:

Vf = final velocity = 0 (the plane comes to stop)

Vo = initial velocity = 24 [m/s]

a = desacceleration = 3.9 [m/s²]

t = time [s]

Note: The negative sign of the acceleration means that the plane is decreasing its velocity.

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.
