Amass resting on a horizontal, frictionless surface is attached to one end of a spring; the other end is fixed to a wall. it takes 3.6 j of work to compress the spring by 0.13 m. if the spring is compressed, and the mass is released from rest, it experiences a maximum acceleration of find the value of (a) the spring constant and (b) the mass.

(a) The spring constant is 426N/m

(b) The mass is 5.65kg

Explanation:

(a) Energy stored in the spring (E) = 3.6J, extension (e) = 0.13m

E = 1/2Ke^2

3.6 = 1/2 × K × 0.13^2

K (spring constant) = 3.6×2/0.0169 = 426N/m

(b) F = Ke = 426 × 0.13 = 55.38N

Assuming the maximum acceleration (a) is 9.8m/s^2

Mass (m) = F/a = 55.38/9.8 = 5.65kg

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
