Question

A bus increase its speed from 20km/h in 10 seconds What is the acceleration of bus?​

Answer 1

Initial velocity = u

= 20km / hr

= 20 x 5/18

= 5.56 m / s

Final velocity = y = 50 km / hr

= 50 x 5/18

= 13.89 m / s

Time = t = 10 sec

Acceleration = aa

= ( v- u) / t (13.89 - 5.56) / 10 = 0.833 m / s
