Answer:
h = 147 - 16t^2.
Step-by-step explanation:
Use the following equation of motion
h = ut + 1/2 gt^2 where h = height, u = initial velocity , g = acceleration due to gravity and t = the time.
So here we have:
h = 14t + 1/2 * -32 * t^2
h = 14t - 16t^2

Explanation:
Write the standard form of the line that goes through
(

,
1
)
and is perpendicular to
y
=
−
2
3
x
+
4
.
The equation
y
=
−

x
+
4
is in slope intercept form
y
=
m
x
+
b
where
m
= slope and
b
= the
y
intercept.
The slope of this line is then
m
=
−

A perpendicular slope is the opposite sign reciprocal. So, we change the sign of
−

and switch the numerator and denominator.
