Answer 1

Answer:

Explanation:

See I think that since I am just an helping hand you should skip my answer I am new here so please don't rate me as bad.

Answer 2

Answer:

The body does no start from rest

Explanation:

v11 = u + at1

v22 = u + at2

v33 = u + at3

We know that Vavg = Mean velocity

V1 = [u + v11]/2 = [u + u +at1]/2

   = u +1/2at1

V2 = [v1 +v2]/2

     = u +a[t1 +t 2]/2

V 3 = u + a[2t1 +2t2 +t3]/2

v1-v2 = t1 + t2

v2 -v3 = t2 + t3
