(a) (1/2)kx^2 = (263.1 N/m)*(0.0411 m)^2

= around 0.4 J but use a calculator.

(b) (1/2)kx^2 = (263.1 N/m)*(0.0284 m)^2

= around 0.2 J but use a calculator.

(c) Zero.(0 J)

PE = (1/2)kx^2. You know k and you know x. All you have to do is convert between m and cm. (1x10^2) cm = 1 m, square both sides, (1x10^4) cm^2 = 1 m^2. Direction doesn't matter.

how about b and c
