Question

a bus starts from the rest and attains 40 kilometre per hour - 1 velocity after 10 second calculate the acceleration of the in kilometre - 2 and
ms-2

Answer 1

Acceleration = (v - u) / t
= (40 kmph - 0 kmph) / [10 s × (1 hr / 3600 s)]
= 1400 kmph

or

Acceleration = (v - u) / t
= [(40 - 0) × 5/18 m/s] / 10 s
= 1.11 m/s^2
