a bus starts from rest and attains 40 km per hour velocity after 10 se

1.	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» *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 .

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»

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 .
