(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

An object of mass m is launched at speed v from point P on horizontal ground at an angle of elevation of 45 degrees, as shown in the picture. When the object reaches point Q the magnitude of the change in momentum of the object is ?

2. Relevant equations

Change in momentum of the object

mv - mu

3. The attempt at a solution

Honestly, I really don't know how to start

All i know is use the formula of the change of momentum

But then the angle 45 degrees I really dont know where to put..

Can somebody help me

Sorry for not attempting

Is because I am a bit blur..

Lastly the options for this question is

A : Zero

B : 1/2 mv

C : 2mv

D : 4mv

Thanks so much..
