Mechanics M1: Post your doubt here

[daviruss]

Speed at top was 20

hmmm u sure cuz p/v 30000/2000 = 15 m/s

 

[balay]

Speed at top was 20

what was the angle u calculated in that question?

 

[hussamh10]

what was the angle u calculated in that question?

3.43 smthng like that

 

[daviruss]

3.43 smthng like that

hehe u wrote 30 before and u edited and yup ur right man shift sin(30/500)

 

[hussamh10]

hmmm u sure cuz p/v 30000/2000 = 15 m/s

did you subtract the resistance?

 

[Asheeta]

Oh come on guys there is no use crying over spilled milk!

 

[daviruss]

did you subtract the resistance?

yup i did which was 1000N am sure thts what we all got

 

[iKhaled]

yup i did which was 1000n am sure thts what we all got

umm bro how did u get F to be 2000 ?

spilled milk ?

 

[hussamh10]

yup i did which was 1000N am sure thts what we all got

may be i have done sme pen mistake dont know

 

[daviruss]

umm bro how did u get F to be 2000 ?

dude the friction was 1000N u need to find DF( driving force) so DF-mgsin(theta)-Fr=ma

 

[mhalvi]

Easy paper.......!!!
Went really good Alhamdulillah

 

[hussamh10]

umm bro how did u get F to be 2000 ?

F was 1500 i guess

 

[daviruss]

may be i have done sme pen mistake dont know

tis ok dude u will get marks for working

 

[daviruss]

nope 1000 N hehe anyways GL i may we all get the grade we want

F was 1500 i guess

 

[hussamh10]

nope 1000 N hehe anyways GL i may we all get the grade we want

Yeah Chill Now

 

[Asheeta]

mea

spilled milk ?

Nyways JFI

man i did a silly mistake that ruined my whole question..i calculated the acceleration on the top 0.4 instead of 0.2 and continued my working like that how many marks u think i will get off ?
