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 (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 k, pulled back a distance d, and released. A block of mass M is attached to a spring with a spring constant 2k, pulled back a distance d, and released. A block of mass M is attached to a spring with a spring constant k, pulled back a distance (1/2)d, and released.

Explanation / Answer

In this question mass does not matter ,

F= kx

1. F= k×d = kd

2. F= k/2×2d= kd

3. F= kd

4. F= 2kd

5. F= k×d/2= kd/2

So we rank

1. 5,1,2,3,4 2. 5,2,3,1,4 3. 5,3,2,1,4

Rank 1, 2 3 are equal.
