5. Solve for the unknown variable (A).
\\
Therefore, the acceleration needed to increase the
speed of a car from 16.67 m/sec (60 kph) to 27.78
m/sec (100 kph) in a distance of 100 m is
approximately 2.47 m/s

.
Because the variable A in the equation is linear we
know that we need not look for any other solutions.
Plot the
equation
The Plot view shows one graph for each side of the
selected equation. You can choose any of the
variables to be the independent variable.
The current equation is .
Select A as the variable. The plot view will now plot
two equations. One of these is , with
, that is, . This graph will be
a horizontal line. The other graph will be
, with and , that
is, . This graph is also a line.
The desired solution is the value of A where these two
lines intersect.
4. Enter the values for
the known variables.
