a body of mass 5 kg is acted upon by a variable force the force varies

1.	a body of mass 5 kg is acted upon by a variable force the force varies with the distance covered by the body what is my speed of the body when the body is covered 25m assume that body starts from rest.
Answer» F =MA 10 = 5a a=2 V^2 - u^2 =2as V^2 = u^2 + 2as V^2 = 0 + 2(225) In AB PART of journey V^2 = 100 V=10m/sec

Answer»

F =MA

10 = 5*a

a=2

V^2 - u^2 =2as

V^2 = u^2 + 2as

V^2 = 0 + 2(2*25)

In AB PART of journey

V^2 = 100

V=10m/sec
