Question

a bus starting from rest moves with a uniform acceleration of 0.1 metre per second square for 2 minutes . find the speed acquired and the distance covered by the body?

Answer 1

Here, acceleration a = 0.1 ms-2

Time t = 2min = 2 x 60 = 120s

Initial speed u = 0

(a) From Ist equation of motion, speed acquired, v = u + at


= 0 + 0.1 x 120

= 12 ms-2

(b) From IInd equation of motion,

Distance travelled,

image001

= 0.1 x 60 x 120 = 720

➧ 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
