Question

A train starting from Railway Station train speed is 40m/h in 10m. find it acceleration ​

Answer 1

Answer:

We know that a=v-u÷t

Explanation:

So,

Final velocity,v=40m/h

Initial velocity, u=0(because train starting from rest).

Time=10m

Acceleration =?

Now,a=v-u÷t

=a=40-0÷10

=40÷10

=4m/s.

Answer 2

Answer:

So train starting from rest

u = 0

v = 40m/h

t = 10m

a = ?

v = u +at

40 = 0 + a ×10

40 = 10a

a = 40/ 10 = 4

acceleration of train is 4 meter per hour square
