Forces — practice question

A spring is hung from a clamp, and Fig. 1.1 shows a pointer fixed to the spring’s lower end. A student hangs weights of different sizes from the spring and notes the metre-ruler readings.
(a(i))[1]

From Fig. 1.2, find the metre-ruler reading when: 1. no weight is hanging from the spring 2. a weight of 5.6 N is hung from the spring.

(a(ii))[1]

Calculate the spring’s extension when the attached weight is 5.6 N.

(b)[2]

Using the values obtained in (a), calculate the spring constant for the spring.

(c(i))[1]

Calculate the weight of the object.

(c(ii))[3]

Calculate the acceleration of the object immediately after release.
