Solution

The correct option is D

1.83 m s–1


Step 1 Assigning variables

let x= Distance covered by bus , a= acceleration , t = time

Initial speed of the bus, u = 0

v= velocity of person

Step 2 Calculation

Using equation of motion

x=12at2x=120.1(30)2

Equating distances

x+10=vt

12(0.1)(30)2+10=v(30)55=v(30)v=1.83ms-1

Answer Option D is correct.
