Question

after a condition with ideal spring a body of mass 8 gm moving with a constant speed of 10ms comes to rest and force constant equals to 200 dyne cm if the total kinetic energy of a body is paint in compressing the spring find the compression​

Answer 1

Answer:

which class questions tell me what you think about it

Answer 2

Answer:

Given−

m=0.1kg

v=10m/s

k=1000N/m

As moving object strikes on the spring, the kinetic energy of object is used in compressing the spring.

Kinetic energy of object = Work done in compression

1/2mv

x=0.1m

Compression produced in the spring is 0.1m.

Hence,

option (B) is correct answer.
