How was the M1 paper?

[Shehan Livera]

Post what you think that you will get for the M1 paper.

 

[bas007]

A will be 55

 

[kmkm20092008]

there is no A* in M1 , lol

 

[Shehan Livera]

there is no A* in M1 , lol

what if a person get above 90?

 

[IGCSE Abdullah]

what if a person get above 90?

out of range!! lol

 

[IGCSE Abdullah]

A will be 55

How do u know???

 

[holloz17]

you can't get A* at AS level, how did everyone do on question 5 parts C and D, the car and motorcycle question, i think part C was find the time for the motorcycle from the first traffic light to point A, and part D find the acceleration?

out of range!! lol

i was talking from 100%

 

[holloz17]

i was talking from 100%

can anyone remember what they got for 5c, i think it was find the time of the motorcycle from the first traffic light, to point A?

 

[Hamzeh S]

i did really bad Did some stupid mistakes , didnt know the moment question

t

can anyone remember what they got for 5c, i think it was find the time of the motorcycle from the first traffic light, to point A?

time was 70 seconds... how i did it was work put time for car to travel 990m i got 60 seconds for motorcycle its t for car+ 10 so 70 seconds and acceleration i got 0.4

 

[Hailstorm94]

moments question was hard!!!! i left it blank only drew diagram and rp+rq = 50g+ mg so maybe 1/14 marks

 

[DC1313]

it was annoying from question 5 onwards (speed time, moments, vectors, and that stupid last one.)

 

[holloz17]

t time was 70 seconds... how i did it was work put time for car to travel 990m i got 60 seconds for motorcycle its t for car+ 10 so 70 seconds and acceleration i got 0.4

would you be able to show your workings? because i too worked out the time for the car to travel 990m, but i got 92 seconds not 60 :/

 

[Hamzeh S]

moments question was hard!!!! i left it blank only drew diagram and rp+rq = 50g+ mg so maybe 1/14 marks

actually he said on the point of tilting so only RP or RQ hahaha :/ i may get 0 in this question and the speed time graph maan i did it all wrong except drawing

 

[holloz17]

can someone explain how they found the time of the motorcycle?? i worked out the time for the car and then added 10 seconds on.... i used u=0, v=22, s=990, and i worked out acceleration with v^2=u^2 + 2as, giving 22^2 = 2 x 990a, and a came out as 0.24, then i used v=u+at, and t came out as 92??? :/

 

[IGCSE Abdullah]

what about the last question ??

T in string and acceleration in particles??

timetaken (T) was 105s!!

ok sure will do... we know that that in the first 30 seconds the car traveled 330m.... 30x22/2(triangle)... after that it was at 22m/s for awhile so what i did was 990-330=660... now 660/22 = 30(square so dividing by speed gets time) seconds as well... we know that when the biker met with car speed of car was 22 so it hadnt decelerated upto then... so 30+30=60 now for biker it was 10 more seconds... 60+10= 70...

ok thanks that makes sense :/ but i still dont understand why the way i did it is wrong :L
