Block 1 is attached to a spring and oscillates on a horizontal frictionless surface. When Block 1 is at a point of maximum displacement, Block 2 is placed on top of it from directly above without interrupting the oscillation, and the two blocks stick together. How do the maximum kinetic energy and period of oscillation with both blocks compare to those of block 1 alone?

A) Max KE: Smaller; Period: Smaller
B) Max KE: Smaller; Period: Greater
C) Max KE: The Same; Period: Smaller
D) Max KE: The Same; Period: Greater

Respuesta :

Answer:

Explanation:

Period of oscillation ∝ √ m

So period of oscillation is proportional to square root  of mass

So when mass increases , period too will be increased . But the total energy will remain the same as per conservation of energy.

Hence option ( D) is the correct answer.
