Acar travels in a straight line along a road. its distance x from a stop sign is given as a function of time t by the equation x(t)=9t^2-8t^3 m . find the acceleration (in m/s/s) of the car at t = 4.6 s. give answer with two decimal places. don't use the units in the answer box.

Given that the equation of distance "x" of a car travelling in a straight line along a road.

x(t) = 9 t² - 8 t³ meters

acceleration at time "t" = ?

t = 4.6 s

Acceleration = Velocity/ time

Velocity = distance/ time

Acceleration = distance / time²

Acceleration = x / t²

a (t) = (9t² - 8t³)/ t²

a (t) = 9 - 8t

a (4.6) = 9 - 8 (4.6)

a (4.6) = -27.80 m/s²

The acceleration of car at time "t" is 27.80 m/s².

the masses of the objects and the distance between them

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.
