Answer:
(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
