Question

a bus starts from rest and attains 40 km per hour velocity after 10 second calculate the acceleration of the bus in kilometre per hour per second and metre per second​

Answer 1

Given:

Velocity of bus (v) = 40km/h

40/60×60

= 40/3600

= 1/90km pers

Time taken (t) = 10s

Acceleration = v/t

= 1/90/10

= 1/900km/second square

or 1000/900

= 10/9 m per second square

10s = 1/36h

so a= 1/9/1/36

= 4km/hour square

so the answers are 1/900 km per second square , 10/9 m per second square and 4 km per hour .
