You're already pretty close, you need to correct the signs as 2pi/3 is 120o, not 60o.
Then you can just do x/y=a/b (a and b are the fixed values involving r), the r's cancel and you can rearrange.

# Laws of Falling Bodies
## Homework Statement
If a falling object overcome 72 metres in 6 second, how much distance it overcame in first 3 second.
s = ut+(at^2)/2
## The Attempt at a Solution
Here,
s = 72 m
u = 0
t = 6s
a = ?
We know,
s = ut+(at^2)/2
Or, 72 = 0*6 + (a*6^2)/2
Or, 72 = 36a/2
Or, 72 = 18a
Or, a = 4 ... | HuggingFaceTB/finemath | |
