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
