Question

a body starts from rest and then covers 30m in 5 seconds . calculate the increase in the velocity per second .

Answer 1

distance(s)=30m
timetaken(t)=5sec
Now,
v=s/t=30/5=6 m/s

Answer 2

U=0

T=5sec

D=30m

A=?

Second equation =ut+1/2 at square

S=ut+1/2at square

30=0*5+1/2a 5 square

30=0+1/2a *25

30=1/2a*25

30=25/2=a

A=30*2/25

A=12/5 m/s square.
