Uhh we made 2 simultaneous equations for the distance of 100 and 248 considering s-ut+1/2at^2
and then solved them
so a was 3 and u was 19 i think
and then solved them
so a was 3 and u was 19 i think

Everyone in my batch got different weird answers that's why I'm here checkinghave u checked your answers with your batch tho I hope we are correct

yes something involving 231 or 312 i dont remember eitherYou can use average speed distance time method for constant velocity i think
I'm not sure if you'll get an ECF
But you'll get your marks for finding u
and the distance CD?
312 m i think
Don't clearly remember
44 nearany guesses on grade threshold for paper 42 anyone.
some people got the value 5.20 for mew instead of 0.577. What they did was reverse the direction of P such that now it acts down the plane. So the two simultaneous equataions become P(min)+20gsin(60)=20gcos(60)mew and P(max)=20gcos(60)mew+20gsin(60) and then P(max)=2P(min).. Did the question specify the direction of the force P or no?

no mew can be more than 1 actually Edit: I got 2.06*10^6Wno, but mew can't be more than 1 :/
ok, my u was also 19 and the method of finding s was the same. and the distance was 312 too. Last answer was 2.1. What power did you get for the second question?
No they didnt specify the direction, but i think they said P was applied to give equilibrium, so if mgsinx and friction were acting, and if friction was insufficient to resist mgsinx, P was applied to help F overcome mgsinx.some people got the value 5.20 for mew instead of 0.577.

206,000 Wsomeone tell the correct answer for power in question 2 i want to confirm too
2060,000 my dude.206,000 W
r u from lgs jt?My answer for Q2 was some big number with 2 at the start but several mates of mine got like 36 something. As for the coefficient of friction, both methods to find coefficient of friction appear to be correct and logical but the only reason you might not choose the method that got the answer 5 is that, 5 is too big to be a coefficient of friction,
How could you possibly knowr u from lgs jt?
theetay udhar hi peeda hotay hen, knew it dude.How could you possibly know
