The arc will be a proportion of the circumference.
The circumference is 2πr = 6.28(15 ft) = 94.2 ft
The proportion is 45/360
Then the arc is (45/360)*94.2 ft = 11.78 ft
Firstly, you've got to expand the brackets, this becomes;
8a-4= -10a+ 50
You've then got to eliminate the -10a and you do this by adding 10a to both sides,
This then becomes 18a-4=50
You've then got to add 4, to eliminate this, which then becomes 18a=54
You've then got to divide both sides by 18, and this becomes 3.
Therefor, a=3

In the equation F=kx, F is the force, k is the spring constant, and x is the displacement. Plug in and solve:
F=0.3(1.5)
F=0.45N
