Expert Solution
Step 1

Given 

Initial velocity of the particle u=3m/s

                           acceleration a=0.5m/s2

2. The velocity of the particle after 3 sec

        time t=3 sec

we know that v=u+a t

where v is final velocity ,u is initial velocity ,a is acceleration ,t is time

now final velocity after t=3 sec

                     v=3+0.5(3)v=4.5 m/s

2.2  The final velocity after time t will be 

v=u+a tor v=3+0.5(t) m/s
