Question

A train is travelling relative to the earth at velocity of 15 m/s. A person in the train is walking relative to train at a velocity of 1 m/s in the direction of motion of the train. The velocity of the person relative to the earth is in m/s Numeric Answer

Answer 1

Answer:

SRGLGHBDGGBHGHLHBGDHGDLGDLHLDG

Explanation:

V train wrt earth = 15 m/s

V person wrt train = 1 m/s

Therefore,

V person wrt earth = V person wrt train + V train wrt earth

= (15 + 1) m/s

= 16 m/s (ans)

IT IS HELPFUL I THINK SO

Answer 2

Answer:

Velocity of person wrt earth is 16 m/s

Explanation:

As per the question,

We need to find the relative velocity of person wrt earth.

Given info are:

Velocity of train wrt earth = 15 m/s

Relative velocity of person wrt train = 1 m/s

So, according to the formulas:

Relative velocity of person wrt train = Velocity of person wrt earth - Velocity of train wrt earth

(since motion dir. is same)

1 m/s = Velocity of person wrt earth - 15 m/s

Velocity of person wrt earth = 16 m/s

Thus,

Velocity of person wrt earth is 16 m/s
