at 25:45 , I understood why we choose C but why not D? cuz like the mass will be the same right hence only the velocity is changing per unit time or is it like the question didnt specify that the mass remains same so we are not selecting D?
why is stopping force used intsead resultant force... how do we know what to use?? maybe is it because the stopping force is the one changing the momentum.. and not resultant force
The harbor is moving with a constant speed of 16.4m/s And according to newton's first law, there is no force to the right, so resultant if you want to find out is 0-920000 = -920000N

Love the explanations!
👍
Hey there ,
where can I find the handouts?
thankyou for such a good explanation
Thanku
Where can i find handout
can u pls share ur one note

You still need to multiply mass to obtain resultant force. Change in momentum uses both mass and velocity.

30:28 Miss that force we took to calculate must be the resultant force ryt
Not the stopping force
why is stopping force used intsead resultant force... how do we know what to use?? maybe is it because the stopping force is the one changing the momentum.. and not resultant force
i went on to calculate the forward force.. so that i can find resultant force.. lol
@@brocklesnar4577 same I don't understand that as well
