SATHEE: Work Energy And Power Question 94

Work Energy And Power Question 94

Question: Two equal masses $m_{1}$ and $m_{2}$ moving along the same straight line with velocities + 3 m/s and ? 5 m/s respectively collide elastically. Their velocities after the collision will be respectively [CBSE PMT 1994, 98; AIIMS 2000]

Options:

A) + 4 m/s for both

B) ? 3 m/s and +5 m/s

C) ? 4 m/s and + 4 m/s

D) ? 5 m/s and + 3 m/s

Show Answer

Answer:

Correct Answer: D

Solution:

As $m_{1} = m_{2}$ therefore after elastic collision velocities of masses get interchanged i.e. velocity of mass $m_{1} = - 5 m / s$ and velocity of mass $m_{2} = + 3 m / s$
