Question

class 9 motion chapter numerical
A trian starting from a railway station and moving with uniform acceleration attains a speed 40km h-1 in 10 minutes.Find it's acceleration
​

Answer 1

Answer:

0.0185 m/s^

Explanation:

given= time = 10 minute

convert into seconds i.e. 10*60

= 600 sec

intial Speed= u = 0m/s-1

final speed of Train as v=

40km h -1. = 40*1000/3600

= 11.1 ms- 1

now acceleration is given by relation

a= v-u/t

putting the values

11.1-0/600

= 0.0185 m/s^

hence the acceleration is 0.0185 m/s^

hopefully it will work ☺️☺️☺️
