A 3 kg block, attached to a spring, performs linear SHM with the displacement given by x = 2 cos (50t) m. Find the spring constant of the spring.

Answer»

Data : m = 3 kg, x = 2 cos (50t) m 

Comparing the given equation with x = A cos ωt,

ω = 50 rad/s 

ω2 = k/m 

∴ The spring constant, 

k = mω2 = (3)(50)2  

= 3 × 2500 = 7500 N/m
