Question

Five different experiments are carried out. In each experiment, a block is attached to a horizontal spring. The block is pulled back a certain distance and released. The block oscillates back and forth on a frictionless surface. Rank the amplitude of oscillation for each of the following situations. (Rank the smallest amplitude as 1). A block of mass M is attached to a spring with a spring constant k, pulled back a distance (1/2)d, and released. A block of mass M is attached to a spring with a spring constant k, pulled back a distance d, and released. A block of mass (1/2)M is attached to a spring with a spring constant k, pulled back a distance d, and released. A block of mass M is attached to a spring with a spring constant (1/2)k, pulled back a distance 2d, and released. A block of mass M is attached to a spring with a spring constant (1/2)k, pulled back a distance d, and released.

Explanation / Answer

Amplitude of oscillations:
±1/2 d
± d
±d
±2d
±d

so, according to amplitude

rank 1 = block 1

rank2 = block 2,3,5

rank 5 = block 5
