Answer:
300 N/m
Explanation:
given,
Load attached to the spring, W = 54 N
length of stretch of the spring, x = 0.15 m 
spring constant= ?
Force applied on the spring is calculated by the equation 
 F = k x
where k is the spring constant
 x is the displacement of the spring due to applied load
 now,
54 = k × 0.15


hence, the spring constant is equal to 300 N/m
