Work Energy And Power Question 115
Question: A body at rest breaks up into 3 parts. If 2 parts having equal masses fly off perpendicularly each after with a velocity of 12m/s, then the velocity of the third part which has 3 times mass of each part is [UPSEAT 2001]
Options:
A)
B)
C)
D)
Show Answer
Answer:
Correct Answer: D
Solution:
The momentum of third part will be equal and opposite to the resultant of momentum of rest two equal parts let V is the velocity of third part.
By the conservation of linear momentum
therefore
