Work Energy And Power Question 148
Question: The block of mass moving on a frictionless horizontal surface collides with a spring of spring constant and compresses it by length . The maximum momentum of the block after collision is
Options:
A)
B) zero
C)
D)
Show Answer
Answer:
Correct Answer: D
Solution:
[d] When block of mass M collides with the spring , its kinetic energy gets converted into elastic potential energy of the spring.
From the law of conservation of energy,
Where v is the velocity of block by which it collides with spring.
So, its maximum momentum.
After collision, the block will rebound with same linear momentum.
