No it would not be static friction.
Answer:
176.44 m
Explanation:
y = (vertical vi)t + (1/2)gt^2
315 = 0 + (1/2)(9.8)t^2
t = 8.02s
x = (horizontal vi)t + (1/2)at^2
x = (22)(8.02) + 0
x = 176.44 m
Stan’s displaceent is 0 km because he ends his walk where he started.
Amplitude: the height of the wave
wavelenght: the distance betweeen adjacent crests
