Question

mathematical prove for newtons third law of motion

Answer 1

from secomd eqn of motion
s=ut+1
_at2 --------1
2
v=u+at
at= v-u
s=u×(v-u)+1 a/( v-u)
___ _ ___
a 2 a/
s = uv-u2 +( v-u)2
_____ ___
a 2a
s= 2×(uv-u2) +(v-u)
___________
2a
s= -2u2+ u2+ v2
__________
2a
s= -u2 + v2
______
2a
2as= v2 - u2
v2- u2 =2as
v2= u2 + 2as
