Sam and George are riding in separate cars on the freeway. The lanes they are driving in are adjacent. We choose our coordinate system so that both are traveling into the positive x-direction. Sam travels at 65 mph and George travels at 72 mph. (a) What is Sam’s velocity relative to George? (b) What is George’s velocity relative to Sam?

Respuesta :

Answer:

(a) Relative speed of Sam = -7 mph

(b) Relative speed of George = 7 mph

Explanation:

We have given speed of Sam 65 mph in north direction.

And speed of George is 72 mph also in north direction

We have find the relative velocity of both Sam and George

(a) Speed of Sam relative to George = speed of Sam - speed of George = 65 -72 = -7 mph

(b) Speed of George with respect to Sam = speed of George - speed of Sam = 72-65 = 7 mph
