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 maximum force on the block for each of the following situations. (Rank the smallest force as 1).
1 2 3 4 5  A block of mass M is attached to a spring with a spring constant 2k, pulled back a distance d, and released.
1 2 3 4 5  A block of mass 2M is attached to a spring with a spring constant k, pulled back a distance d, and released.
1 2 3 4 5  A block of mass M is attached to a spring with a spring constant k, pulled back a distance d, and released.
1 2 3 4 5  A block of mass M is attached to a spring with a spring constant k, pulled back a distance 2d, and released.
1 2 3 4 5  A block of mass M is attached to a spring with a spring constant (1/2)k, pulled back a distance 2d, and released.

Explanation / Answer

The force = spring constant x extension. The maximum force occurs when the spring is at maximum extension. This mass makes no difference.

1. F =(1/2)kd
2. F = kd
3. F = k(1/2)d = (1/2)kd
4. F = kd
5. F = (1/2)k(1/2)d = (1/4)kd

In order:smallest 1st:
5
1 ans 3 equal
2 and 4 equal
