A man with a wristwatch on his hand falls from the top of a tower. Does the watch give correct time during the free fall? 

When a mass of 1 kg is suspended from a vertical spring, its length increases by 0.98 m. If this mass is pulled downwards and then released, what will be periodic time of vibration of spring? (g = 9.8 m/s²)

A block of mass 'm' moving with velocity (v) collides perfectly inelastically with another identical block attached to spring of force constant K. What will be the amplitude of resulting SHM?

A spring having a spring constant 1200 Nm^–1 is mounted on a horizontal table. A mass of 3 kg is attached to the free end of the spring. The mass is then pulled to a distance of 2.0 cm and released. Determine Maximum acceleration of mass.

A spring balance has a scale that reads from $0$ to $50 \mathrm{kg}$. The length of the scale is $20 \mathrm{cm}$. A body suspended from this spring, when displaced and released, oscillates with a period of $0.6 \mathrm{s}$. What is the weight of the body?
