Answer:
80 km is the acceleration of the bus
Answer:
We know that
Here u = 80km/h = 22.2 m/s
and v = 60 km/h = 16.6 m/s
t = 5 sec
Thus a = = = 1.12 m/s (approx)
Note:- You might think why I haven't put minus sign. Acceleration with "-" sign refers Retardation or deacceleration. So If retardation is asked, write without minus sign. Else with minus sign
