Question

A sheep is moving at a velocity of 2mph relative to a train and the train is also moving at 2mph relative to ground then what will be the velocity of the sheep??

Answer 1

Answer:

The velocity of sheep will be 4 m/h.

Explanation:

Given that,

The velocity of sheep relative to a train$v_{st}=2 m/h$

The velocity of train relative to a ground $v_{tg}=2 m/h$

We need to calculate the velocity of the sheep

The velocity of sheep relative to a train is

$v_{st}=v_{s}-v_{t}$

$2=v_{s}-v_{t}$.....(I)

The velocity of train relative to a ground is

$v_{tg}=v_{t}-v_{g}$

$2=v_{t}-0$

$v_{t}=2\ m/h$

Put the value of $v_{t}$ in equation (I)

$2=v_{s}-2$

$v_{s}=4\ m/h$

Hence, The velocity of sheep will be 4 m/h.
