Question

The speed of a bus increases from 20km/hr to 40km/hr in 10 sec what is it's acceleration

Answer 1

hey dear
here is your answer

given data :

initial velocity (u) = 20 km/hr or 5.55 m/s

final velocity (v) = 40 km/hr or 11.11 m/s

time taken (t) = 10 seconds

to find : acceleration (a)

solution :

by using 1st equation of motion

v = u+at

11.11 = 5.55+10a

10a = 5.56

a = 0.556 m/s^2

hope it helps :)
