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 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 (1/2)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
The maximum force on the block can be calculated using the Hooke's law F = kx Here, k is the spring constant and x is the compression or stretched distance i) Spring constant is k , stretched distance is d/2 F1 = k (d/2) =1/2 (kd) Rank - (1) ii) Spring constant is 2k , stretched distance is 2d F2 = 2k (2d) = 4 (kd) Rank - (3) iii) Spring constant is 1/2k , stretched distance is d F3 = 1/2k (d) = 1/2 (kd) Rank - (1) iv)Spring constant is k , stretched distance is d F4 = k (d) = kd Rank - (2) v)Spring constant is k , stretched distance is d F5 = k (d) = kd Rank - (2) F2 > (F4 = F5) > ( F1 = F3 ) F3 = 1/2k (d) = 1/2 (kd) Rank - (1) iv)Spring constant is k , stretched distance is d F4 = k (d) = kd Rank - (2) v)Spring constant is k , stretched distance is d F5 = k (d) = kd Rank - (2) F2 > (F4 = F5) > ( F1 = F3 ) F4 = k (d) = kd Rank - (2) v)Spring constant is k , stretched distance is d F5 = k (d) = kd Rank - (2) F2 > (F4 = F5) > ( F1 = F3 ) F5 = k (d) = kd Rank - (2) F2 > (F4 = F5) > ( F1 = F3 )Related Questions
