Umm I got the coefficient of friction as 1.13.. and my resultant was 53. something. And yeah.. total time was 155. The thrust question i dint get. the mass m was 0.3.. any1 else with similar answers?

total time was 155.
I dont remeber the other values :/

N was 54.2 and coefficient of friction was .126-.13, m was 0.3

 

[xIshtar]

Got my N as 50 something
I got 0.14 as my coeff.
155s seconds.
0.125N for the thrust in the last question
m for question 1 was 0.3kg for me

Hope you all did good

That's exactly what I got, and btw xlshtar m was not in kilograms, it was just a constant, so it didn't have any units.

yup! no units

whats the answer for distance we had 2 find find when the ball fell into the soft ground and acceleration too?

hy what did u get d acceleration nd distance when d ground is soft nd d ball sinks?

i messed up dat question i think i got something lyk 0.3 but i think its wrong... m not sure...

 

[simim]

in the vectors question do we subtract B from S? and nd den calculate?

i messed up dat question i think i got something lyk 0.3 but i think its wrong... m not sure...

i got 0.316 m but i want to know whther d accelration is negative or positive?

maybe you didnt , the answer was like 0.3136 then you round it to 0.3 or 0.31

 

[étudiante]

the acceleration is negative ofc... it will slow it down
0.136? i got dat too i think! does dat mean it right?

dats wat i did tho i dunno if i did B-S or S-B

YAAAY den! i thot i lost 3 marks here
thanks for confirming

iim sure d answr is0.316m but i wasnt sure of the acceleration

sum of dem did 5000-4g=4a nd got a as positive

 

[étudiante]

sum of dem did 5000-4g=4a nd got a as positive

but i think its negative cuz its decelerated by the impact

guys for the soft ground question, well the acceleration is definitely negative, its experiencing a resistive force, so it's pretty much obvious.
Anyways my acceleration was something like -2000, I can't really remember right. and the distance was in fact 0.3

YAY YAY YAY! *jumps aroud the house* the acceleration WAS negative and i got it close to -2000 (rounded) and i got 0.3m as the distance
