Answer 1

Hey mate!

Here's your answer!!

In BUS FRAME-

Velocity of man = 10 m/s

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 × at2

48 = 10t - 1/2 × t2

Solving the equation, we get

t = 12 sec or t = 8 sec

Therefore, the minimum time is 8 seconds.
