Question

lpz help me !!my question ::1) what arrow is doing ? 2) what is 'f' in these equation

Answer 1

BRO HERE COMES THE ANS:-

ACCORDING TO THE LAW OF CONSERVATION OF MOMENTUM WE HAVE :-

M1U1 = M2U2

WHICH MEANS THE MOMENTUM OF THE SYSTEM BEFORE AND AFTER THE COLLISION REMAINS THE SAME NO MATTER WEATHER AN OBJECT HAVING SMALLER MASS OR GREATER MASS❗❗

BECAUSE

M = mass of body A

WHICH IS SMALL SO ITS U WILL BE GREATER AND VICE VERSA ❗

SO FROM THIS WE KNOW THAT MOMENTUM REMAINS THE CONSERVE❗

BY SECOND LAW OF MOTION OF NEWTON WE KNOW THAT FORCE WHEN APPLIED TO BODY PRODUCES ACCELERATION SO SAME IS THE CASE HERE::-

WHEN EXTERNAL FORCE APPLIED THE BODY MOVES IN THE DIRECTION OF THAT MOTION❗

SO FROM GIVEN FIG =

F1 = (---->)

F2= (----->)

THEY BOTH REPRESENTS MOTION OF BODIES IN THE SAME DIRECTION AND BEING PARALLAL TO EACH OTHER❗❗

PLEASE BRAINLIEST THE ANSWER MATE☺☺❗
