2)V was 30 something
H was 60 Something
3)t was 60 and 40 or something and S was 4hundred something
4)V was something
5) A was 2/3 T was 1.07 and length of string was 1.9something
6) mew was 0.56something ii a was something
7) Were all something
Oh and 1) F was twentysomething and G was 56 ?

Q1> G=56
Q2> v=40m/s h=80m
Q6>co effiecient of friction = 0.571
Q?>length of string 1.42
t=1.066 a=0.6667
a=o at time t=40 and t=60 distance =440


ANYONE WITH SIMILAR ANSWERS?

i first found the speed of B when it reached which came out to be 1.871. (square root of 3.5) then used v^2=u^2+2as to find the distance P travelled and then subtracted that distance from 2.5 to get the length of string.
The acceleration when it was attached to the
I just solved it and I'm getting 1.9524m for my length of string.

T=1.0666...
a=2/3 (for 0.7m), then 2.8 (after the string breaks)

v (when string breaks) = *root* (2 x 2/3 x 0.7) = 0.96609
then it increases to 2
So
2^2 = 0.96609^2 + 2(2.8)s
s = 0.5476

So the length of string will be 2.5-0.5476 = 1.9523
Um I got 1.94 , maybe because I rounded up some values so will I still get marks?
