Question

Block and Spring Force Ranking Due in 5 hours, 48 minutes 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 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 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 (1/2)k, pulled back a distance d, and released Submit Answer Tries 0/10

Explanation / Answer

Given that the block is pulled back a certain distance and released which is attached to a horizontal spring with k, on frictionless surface  

we know that F = -kx = m*a

a. mass M , force constant k , pulled back a distance d/2 and released F = kd/2

b. mass 2M , force constant k , pulled back a distance d and released F = kd

c. mass M , force constant k , pulled back a distance d and released F = kd  

d.mass M , force constant k/2 , pulled back a distance 2d and released F = -k/2*2d = kd

e.mass M , force constant k/2 , pulled back a distance d and released F = k*d /2

Ranking is 1,2,2,2,1
