A jogger runs by a river with a velocity of 7 m s relative to the ground. A leaf floating on the river moves with a velocity of 2 m s relative to the ground (riverbed). What is the velocity of the leaf relative to the jogger?

Respuesta :

Answer:

The velocity of the leaf relative to the jogger is 5 m/s.                    

Explanation:

Given that,

Velocity of jogger wrt to the ground, [tex]V_j=7\ m/s[/tex]

velocity of leaf wrt the ground, [tex]v_i=2\ m/s[/tex]

We need to find the velocity of the leaf relative to the jogger. Let it is equal to V. So, it is given by :

[tex]V=v_j-v_i\\\\V=7-2\\\\V=5\ m/s[/tex]

So, the velocity of the leaf relative to the jogger is 5 m/s. Hence, this is the required solution.
