What change in velocity would be produced on a body of mass 4kg if a constant force of 16 N acts on it for2 s?

F=m(v-u)/t
16=4(v-0)/2
16(2)=4v
V=32/4
V=8

F=m(v-u)/t

16=4(v-0)/2

16=4v/2

16/2. =2v/2

v=8

We all know force equals mass X acceleration F=ma

and also acceleration =final velocity - initial velocity/timea

a=v-u/t

so let join the two formulas together u will get

F=m(v-u)/t

so solve
