Question

a bus starts from rest and attains 40km h-1 velocity after 10 sec. calculate the acceleration of the bus in km h -2 and ms-2​

Answer 1

Explanation:

a= v-u/t

10 sec = 1/6 hr

a = 40- 0/ 1/6

= 40*6kmhr^-2

= 240kmhr^-2

in m/sec

40 km/hr = 100/9 m/sec

a=v-u/t

= 100/9 /10

= 10/9 msec^-2v

or 1.11msec^-2
