Answer:
Check pdf
Step-by-step explanation:
K.E=0.5mv^2
GPE=mgh
The child has both K.E and GPE


g is taken as 9.81
First, you want to identify the slopes and y-int.
Equation 1 = y = -2x + 2
Slope = -2
y-int. = 2 or (0,2)
Equationt 2 = y = 2x + 3
Slope = 2
Y-int. = 3 or (0,3)
To graph, first plot the y-intercepts. Then do the slopes.
Slope = -2
Down 2 over 1 (to the right)
Slope = 2
Up 2 over 1 (to the right)
Then just connect the dots in a line!
Yeah there all right but I have a little hinch for the last and first one
