Question

A train startinf from a railway station and moving with a uniform acceleration attains a speed of 40km/h in 10minutes.Find its acceleration.

Answer 1

 acc= 40 x 5/18 

acc= 200/ 18 

acc= 100 / 9 

acc= 11.1 m/s^2 


time  = 10x 60 sec 

v-u = at 
applying this equation :
a= 11.1 / 600 sec
 
a= 1.8m/s^2
