Dina is walking 0.5 m/s forward on a train that is traveling at 8.0 m/s north. what is dina's velocity relative to the ground?

Dina's velocity relative to the ground is 7.5 m/s.

Explanation:

Given that,

Velocity of Dina v = 0.5 m/s

Velocity of train v' = 8.0 m/s

We need to calculate the Dina's relative velocity

Using formula of relative velocity

Relative velocity=velocity of train - velocity of Dina

Where, v' = Velocity of train

v = Velocity of Dina

Put the value into the formula

Hence, Dina's velocity relative to the ground is 7.5 m/s.
