Y(initial) = 9
V(initial) = 168
V(final) = 0
g(accel-grav) = 32 (in feet per second
squared)
Use the following equation:
V(final) = V(initial) + a(t)
Since this object is moving straight up and
down, a = -32
Enter the knowns into the equation
0 = 168 - 32t
32t = 168
t = 168/9.8
t = 5.25
Now that you know the time it takes to
reach it's maximum, use the general
kinematics equation to solve for final
distance:
y(final) = y(initial) + V(initial)(t) + (1/2)a
(t²)
y(final) = 9 + 168(5.25) + (1/2)(-32)
(5.25²)
= 9 + 882 - 441
= 450 feet
I think it yes the diagonals are congruent but I can’t really tell
All of them
But if u had to pick one I would say addition or subtraction
You are trying to solve what percent of the difference between $26.60 and $18 is of $24.60, so:
$24.60 - $18 = $6.60
24.60x = $6.60
x = 6.60/24.60
x = 0.2683
So the percent increase is 26.83%
