SATHEE: Kinematics Question 387

Kinematics Question 387

Question: Two trains are each 50 m long moving parallel towards each other at speeds $10 m / s$ and 15 m/s respectively. After what time will they pass each other?

Options:

A) $5 \sqrt{\frac{2}{3}} s e c$

B) $4 s e c$

C) $2 s e c$

D) $6 s e c$

Show Answer

Answer:

Correct Answer: B

Solution:

Relative speed of each train with respect to each other be, $v = 10 + 15 = 25 m / s$ Here distance covered by each train = sum of their $l e n g t h s = 50 + 50 = 100 m$
$∴$ Required time = $\frac{100}{25} = 4 sec .$
