Question

how to find final velocity

Answer 1

By applying following formulas;

V=u+at;

v2 =u2+ 2as(2 signifies square)

here;u is the initial velocity;in most of the cases it's zero;since the body starts from rest and v is the final velocity

a means acceleration;(acceleration is the rate of change of velocity)

simple formula to find acceleration is a=v-u/t ;

and finally s means distance ;it can be displacement also
