Question

A train is moving on a straight track with a speed of 35 m/s and its length is 100 m. It overtakes another train of 120 m moving at 25 m/s in the same direction. The time taken by the first train to overcome the second train is

Answer 1

${\huge{\boxed{\mathcal{\red{Answer}}}}}$

= 22s

${\huge{\boxed{\mathcal{\red{explanation}}}}}$

It is given ---->

Length of first train = 100m

Length of second train = 120m

Velocity of first train = 35m/s

Velocity of second train = 25m/s.

Now the time that first train will take to overtake the second train is

Total relative distance / Total relative speed.

______________________________________

Now, coming to question------------->

Total relative distance = sum of Length of both trains = 120 + 100 = 220m.

Total relative speed = difference of speed of both trains = 35-25 = 10m/s.

Now the time taken by first train to overcome second train

$= 220 \div 10$

$= 22s$

Acceleration is called the rate of change of velocity of a body.

Negative acceleration is called retardation.

The acceleration of a body falling under earth's gravity is called acceleration due to gravity.
