Question

a bus starting from rest moves with a uniform acceleration of 0.4m/S² for 4min .find a.speed acquired .b.distance travelled.

Answer 1

Initial speed = 0
time taken = 5 min = 300 s
let final speed = v

then,
use kinematics equation ,
v = u + at
= 0 + 0.2 × 300 = 60 m/s

and distance travelled = S ( let )
use formula ,

S = ut + 1/2at²
= 0 + 1/2 × 0.2 × (300)²
=0.1 × 90000
=9000 m
= 9 km
