Explanation:
x= 0.02 m
E_p= 10.0 J
E_p= 0.5kx^2
10= 0.5k(0.02)^2
solving we get
K= 50.0 N/m
Now
E'_p= 0.5kx'^2
E'_p= 0.5×50×(0.04)^2
E'_p=40 J
b) potential energy is a scalar quantity and it only depends magnitude and not direction so it will remain same in compression and expansion both
c) 20 J = 0.5×50,000×x^2
solving
x= 0.028 m
d) k is 50.0 N/m from above calculation

This is the concept of trigonometry, the direction of the John will be given by:
tan theta=opposite/adjacent
suppose:
a=theta
opposite=4 mph
adjacent=5.5 mph
tan a=4/5.5
a=tan^-1(4/5.5)
a=36
therefore the boat canoe will be moving 36 degrees from East, his direction will be 126 degrees south east
