Ram Shyam are walking on two perpendicular tracks with speed `3ms^(-1)` and `4 ms^(-1)`, respectively. At a certain moment `(say t = 0s)`, Ram and Shyam are at 20 m and 40 m away from the intersection of tracks, respectively, and moving towards the intersection of the tracks.
During the motion the magnitude of velocity of ram with respect to Shyam is

Explanation

The banana peel was thrown from a point in south - west direction relative to car (reference frame of Ram). Shyam is on the ground , the velocity of banana peel relative to him can be considered to be the absolute velocity of banana peel.
`vec v_(Banana//Ram) = vec v_(Banana) - vec v_(Ram)`
`rArr vev v_(Banana) = vec v_(Banana//Ram) + vec v_(Ram)`
=`(-10) hat i + (-10) hat j + (20) hat i = (10) hat i - (10) hat j`
i.,e., the absolute velocity of banana peel is directed toward south - east, or toward shyam as shown in (Fig. 5.75) ( c).
