Question

A particle starts moving with acceleration 2m/s2 .Distance travelled by it in 5th second is?

Answer 1

Here,

a = 2 m/ s²

t = 5s

u= 0

and s = ?

Now,

by the relation,we get

s = ut + 1/2 at²

=0.5 + 1/2 .2 .5.5

= 0+ 5.5

= 25 m

Thus, the required distance travel by the particle is 25 m .
