deduse newton's first law of motion from the newton's second law of motion







plz hurry up

Answer 1

Newton's second law states that F=ma.

Assuming that no external force is being applied on the body, i.e., F=0,

0 = ma

=> 0 = m [(v-u)/t]

=> 0/m = (v-u)/t

=> 0*t = v-u

​=> 0 = v-u

=> u = v

According to Newton's first law of motion, a body moving with a certain velocity continues to move with the same velocity, i.e., u=v; until and unless an external force is applied, which may change the speed of the body.
