Question

a bus degrees its speed from 80km h-1 to 60km h-1 in 5 second find the accelleraton of the bus​

Answer 1

Answer:

the acceleration is -1.11

Answer 2

Answer : acceleration of the bus is -1.11 m/s2

Explanation:

Initial velocity (u) – 80 km/h = 80 × 5/18

= 22.22 m/s

Final velocity (v) – 60 km/h = 60 × 5/18

= 16.67 m/s

By using v = u + at

16.67 = 22.22 + a(5)

16.67 - 22.22 = 5a

- 5.55 = 5a

- 5.55/5 = a

a = - 1.11 m/s2

Hence, the acceleration of the bus is - 1.11 m/s2
