A spring has spring constant `k = 200 N//m`. How much work does it take to stetch the spring
10 cm from equilibrium ?

A spring has spring constant k = 200 N/m. How much work does it take to stetch the sprin from 10 cm to 20 cm from equilibrium ?

A certain spring that obeys Hook's law is stretched by an external agents. The work done in stretching the spring by 10 cm is 4 J . How much additional work is required to stretch the spring an additional 10 cm ?

An extension of 10 cm is produced in a spring (spring constant = 1000 Nm^(-1) ). Calculate the work done to increase the extension from 10 cm to 20 cm.

A 700 g block is released from rest at height h_(0) above a vertical spring with spring constant k=450N//m and negligible mass. The block sticks to the spring and momentarily stops after compressing the spring 19.0 cm. How much work is done (a) by the block on the spring and (b) by the spring on the block ? (c) What is the value of h_(0) ? (d) If the block were released from height 2.00h_(0) above the spring, what would be the maximum compression of the spring ?

A block of mass 4kg hangs from a spring of force constant k = 400 N//m . The block is pulled down 15 cm below equilibrium and relesed. How long does it take block to go from 12 cm below equilibrium (on the way up) to 9cm above equilibrium ?

Two springs with spring constants m K _(1) = 1500 N//m and m K_(2) = 3000 N//m are stretched by the same force. The ratio of potential energy stored in spring will be

A spring has natural length 40 cm and spring constant 500 N//m . A block of mass 1 kg is attached at one end of the spring and other end of the spring is attached to a ceiling. The block is relesed from the position, where the spring has length 45 cm .
