Question

A train of length 500 metre equal along east direction with 15 metre per second. A bird is moving above it along west with speed 10 metre per second then find out the time taken by the bird to cross the train.​

Answer 1

Answer:

We have that,

Length of a train= 500m

Train move east direction = 15m/sec.

& a bird move= 10m/sec.

So,

=) Vr = Vt+ Vb

=)Vr=10+ 15

=) Vr= 25m/sec.

Time taken by the bird to cross the train:

=) 500/25

=) 20 seconds

Answer 2

Answer:

length of the train= 500m

train move toward east direction= 15 m/sec

bird move towards = 10m/sec

So

Vr = Vt+ Vb

Vr = 10+15

Vr = 25m/sec

Time= 500/25

20 seconds.
