Question

A bus of starting from rest moves with uniform acceleration of0.5m/s for 2 minutes find the speed required and the distance travelled .

Answer 1

Initial speed = 0
time taken = 2 min = 120 s
let final speed = v

then,
use kinematics equation ,
v = u + at
= 0 + 0.5 × 120 = 60 m/s

and distance travelled = S ( let )
use formula ,

S = ut + 1/2at²
= 0 + 1/2 × 0.5 × (120)²
=3600 m
= 3.6 km
