Answer:
Explanation:
hi frnd
initial velocity u=+9m/s ;
acceleration a =-2m/s²
in this problem,acceleration's direction is opposite to the velocity's direction
let 't' be the time taken by the particle to, reach a point where it makes a turn along the straight line.
we have,v=u+at
0=9+2t
we get,t=4.5s
now let us find the distance covered in 1/2 second i.e..,from 4.5 to 5 second
let u=0at t=4.5 second
then distance covered in 1/2 s
s=1/2at²
which is equal to 1/4
total distance covered in fifth second of its motion is given by s=2s=2(1/4)=0.5m
