Question

A bus starting from rest moves with a uniform acceleration of 0.1 m/s for 2 mins. Find the a)Speed acquired. b) Distance travelled.

Answer 1

u = 0 m/s

a = 0.1 m/s^2

t = 2 min = 2*60 = 120 s

a) v = ?

As v = u + a t

so, v = 0 + 0.1 *120

so, v = 12 m/s

b) s = ?

As 2as = v^2 - u^2

so, 2*0.1*s = 12^2 - 0

so, s = 144/0.2 = 720 m

➧ u ➾ 0
➧ a ➾ 0.1 m/s²
➧ t ➾ 2 min = 120s

a❱    V ➾ u + at
      V ➾ 0.1 × 120
      V ➾ 12 ms-¹ ...✔

b❱   v² - u² ➾ 2as
  (12)² - (0)² ➾ 2 (0.1)s
          s ➾ 720 m ...✔
