Answer 1

Hey! ! !

Hey my dear friend here is your answer ____________________

ANS - 8 seconds.

Explanation :-

In BUS FRAME-

velocity of man (u) = 10 m/s

displacement (s) = 48 m

Acceleration of man with respect to bus = Acceleration of man - Acceleration of bus
= 0 - (1)
= -1 m/s

Applying second equation of motion,

s = ut + 1/2 at^2

48 = 10t - 1/2*t^2

solving we get, t = 12 sec or t  = 8 sec

therefore the minimum time is 8 seconds.
