Question

a bus decreases its velocity from 80km/h to 60km/h in 5s. Find the acceleration of the bus .

Answer 1

Answer:

• 5/3 m/(s×s)

Explanation:

80km/h - 60km/hr = 20km/hr = 25 m/s

now acceleration = change in velocity per unit time

time = 5 secs

hence, acceleration = 25/(3×5) m/(s×s)

= 5/3 m/(s×s)
