Question

Solid of mass 2 kg moving with a velocity of 10m/s strikes a weightless spring and produces a compression of 25cm calculate the force constant of the spring

Answer 1

Answer:

When the solid mass of mass 2 kg strikes the spring with a velocity of 10 m/s, its kinetic energy get changed into the potential energy in the spring on compressing 25 cm. So, the loss in kinetic energy will be equal to the gain in potential energy in the spring. Hence, the force constant of the spring is 3200 N/m.
