Question

A bus after start covers a distance of 200 m in 10 sec . Find the final velocity of the bus

Answer 1

V = 40m/s Firstly by second equation of motion we will A Acceleration and then by first law of motion we will find V i.e final velocity....

Answer 2

let the initial velocity be u.

final velocity (v)=Distance/time

=200/10

=20m s^-1

therefore v-u=at.

So a=v/t=20/10

=2 m s ^-2.

So,

20-u=2(10)

20-20=u.

u=0.

Therefore the initial velocity u =0 m s ^-1.
