Relative Velocity

Two trains, each 30 m30\text{ m} long are travelling in opposite directions with velocities 5 m/s5\text{ m/s} and 10 m/s10\text{ m/s}. They will cross after

Show answer and solution

Answer: (a)

  1. Opposite directions: relative speed =5+10=15 m/s= 5 + 10 = 15\text{ m/s}
  2. Distance to cross =30+30=60 m= 30 + 30 = 60\text{ m}
  3. t=6015=4 st = \frac{60}{15} = 4\text{ s}, so the answer is (a) 4 s.
