A person strolls inside a train with a velocity of 1.0 m s–1 in the direction of motion of the train. If the train is moving with a velocity of 3.0 m s–1, calculate his (a) velocity as seen by passengers in the compartment, and (b) velocity with respect to a person sitting on the platform.

Answer:

a)1 ms⁻¹

b)2 ms⁻¹

Explanation:

a) since passenger is on the train he can directly see the person who strolls

hence,

           vₐ , passenger                    = 0 ms⁻¹

           vᵇ , the person who strolls = 1 ms⁻¹

        vᵇₐ = vb - va

              = 1-0

              = 1ms⁻¹

b) the observer is sitting on the platform and the person inside the train who strolls as well the train move in the positive direction therefore,

vb , the velocity of the train = 3ms⁻¹

va , the velocity of the person who strolls= 1ms¹

  vᵇₐ = vb - va

        = (+3)-(+1)          

        = 2ms⁻¹
