[omg]

wat formula hv u used 4 uncertainity??????

uncertanity in R/R = uncertanity in V/V + uncertanity in I/I

 

[omg]

k sure...

rehne do i got it

 

[MysteRyGiRl]

here omg

i cnt blv i 4got dis formulaaaaaa thnx loadzzzzzz

rehne do i got it

haha net was stuck yar

u use the equation v^2=u^2+2as
v=20m/s
u=10m/s
s=100m
solve it to get a which is 1.5 m/s^2

tyhanks alot what about question 9 of the same paper ?

oki i have a question why displacement is 100 not 200 ?

q.6 reasons

take the motion the right as positive... now ... whic represent increasing velocity down the slope and then constant velocity till hitting the wall.. the collision was inelastic, so Ek has to be dropped.. which means velocity will decrease... so velocity will be constant but in negative direction with less magnitude as before... this cuts off option D.. as velocity is reduced, it will take more time to reach back at Y again... ball has to stop between XY so climbing to X will again take more time than more.. and velocity has to be 0 at the end as the ball is stopped... B was wrong has it took less time in B's graph...

cuz if u take 200m as displacment u gt 0.75 which is nt in the options

hhhhhhhhhhhhhhhhh smart enough

distance between the two posts is 100m... so what's the point of using 200....???

these are the forces on thr front wheel, the normal reaction force and the friction force, so the resultant would b B
