5.
Move the cursor near the positive (right-side)
intersection. This cursor value will be an initial guess
for
T
.
Press
until
the
cursor is at the
intersection.
The two points of
intersection show that
there are two solutions for this equation. However,
only positive values for
X
make sense, so we want to
find the solution for the intersection on the right side
of the
y
-axis.
6. Return to the Numeric
view.
Note: the T-value is filled in with the position of the
cursor from the Plot view.
7.
Ensure that the
T
value is highlighted, and solve the
equation.
Use this equation to solve for another variable, such as
velocity. How fast must a body’s initial velocity be in
order for it to travel 50 m within 3 seconds
?
Assume the
same acceleration, 4 m/s
2
.
Leave the last value of V as
the initial guess.
