Question

Five different experients 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 (1-5) the maximum force on the block for each of the following situations. Rank the smallest force as 1.

E1 = A block of mass M is attached to a spring with a spring constant k, pulled back a distance d, and released.

E2 = A block of mass M is attached to a spring with a spring constant (1/2)k, pulled back a distance d, and released.

E3 = A block of mass M is attached to a spring with a spring constant k, pulled back a distance (1/2)d, and released.

E4 = A block of mass M is attached to a spring with a spring constant (1/2)k, pulled back a distance (1/2) d, and released.

E5 = A block of mass 2M is attached to a spring with a spring constant k, pulled back a distance d, and released.

Explanation / Answer

1. F = kd

2. F =(1/2)kd

3.  F = k(1/2)d = (1/2)kd

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

5. F = kd
