Answer:
y= -8
Step-by-step explanation:
where m is the slope of the line.
m= 0 which is equal to the slope of the line y=9
because both are parallel.
The side length of the square is also 1.
18 * 3 = 54
4 * 40 = 160
160 + 54 = 214 (From here I will say that she doesn’t have enough money
E=0.5mv^2
That's the formula for kenetic energy. The only unknown we don't have is the velocity. In perticular the final velocity. To find this final velocity we need to use kinematic equations. Since we have the time and I'm also assuming that the initial velocity was zero we're going to use Vf=Vi+at. The acceleration is 9.8m/s^2 because its free fall and we have the time 22s. Vf= 9.8*22=215.6m/s
Now that we have the final velocity plug it in to the kenetic energy formula.
=0.5*3*215.6^2= 69725.04J
