its between my conservation of momentum , or my impulse or my resitution that i got wrong

its between my conservation of momentum , or my impulse or my resitution that ...
i agree with your for PCLM and NLR, but for the impulse you have the directions mixed up
the impulse 5mu should be negative
as it is acting leftwards
and you've said 2u and v are positive, going to the right
paper agate
yeah
jovial zealot
when the two balls collide, A will receive an impulse to the left
so the impulse is negative
paper agate
oh so what about B? would that be positive
jovial zealot
on B yeah
paper agate
i c
jovial zealot
cause the impulse acts to the right
paper agate
i see impulse acts opposite to the direction of the object
or
if it was like successive collisions it would be different
jovial zealot
it just happens in the opposite direction to the collision
paper agate
yeah
jovial zealot
paper agate
ye
jovial zealot
like this
paper agate
yep got it
jovial zealot
good luck with part b
paper agate
ty
jovial zealot
easy peasy bit
paper agate
agrreed
i only needed to do that 9 marker
everything else fopr mechanics is rpetty es
easy
for*
jovial zealot
yeah
jovial zealot
i think stats is pretty bad
discrete random variables and poisson tho are piss easy
paper agate
discrete random variables and poisson tho are piss easy
discrete random vairables are easy
poisson is pretty fine
its continuency tables
paper agate
and chi squared
jovial zealot
ahah
paper agate
i always mix up the hypothesis
h0 becomes h1 and h1 becomes h0
and then expected values
jovial zealot
too many hypothesis tests to remember 😦
