To solve the problem, let’s break down the information given:
- The man’s speed relative to the train is
(walking towards the back). - The train’s speed relative to the ground is
(moving forward).
a) The man’s velocity relative to the train is simply his speed in the opposite direction of the train’s motion, hence:
b) The train’s velocity relative to the ground is:
c) To find the man’s velocity relative to the ground, we take the train’s velocity and subtract the man’s velocity (since he is moving backwards with respect to the forward movement of the train):
So, the final answers are:
a)
b)
c)
a)
b)
c)
