Laws Of Motion Question 209
Question: Two trolleys of mass m and 3m are connected by a spring. They were compressed and released once, they move off in opposite direction and comes to rest after covering distances and respectively. Assuming the coefficient of friction to be uniform, the ratio of distances is [EAMCET (Engg.) 1995]
Options:
A)1 : 9
B) 1 : 3
C) 3 : 1
D) 9 : 1
Show Answer
Answer:
Correct Answer: D
Solution:
When trolley are released then they posses same linear momentum but in opposite direction. Kinetic energy acquired by any trolley will dissipate against friction.
therefore
