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).
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 2M 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 2k, pulled back a distance d, and released.
Explanation / Answer
The block oscillates back and forth on a frictionless surface.
We know that Force =Spring constant *distance (F=kx)
1. F =kd
2. F =2k.d
3.F =2k.2d =4kd
4.F =kd
5.F =k.2d =2kd
3>2&5>1&4
