NOTE - VERY VERY IMPORTANT
THE VALUES IN THE GIVEN TABLE ARE NOT VERY CLEAR. SOME VALUES ARE HALF VISIBLE. I HAVE TAKEN UTMOST CARE TO READ CORRECT VALUES. STILL IF THERE IS ANY MISTAKE, PLEASE LET ME , I WILL CORRECT IT.
PLEASE DO NOT GIVE THUMBS DOWN WITHOUT ANY REASON. MY METHOD IS 100 % FINE.
The ac (centripetal acceleration ) is found as
w = 2 / T
where T = t/50
w = 100 / t
ac = w2r
ac = 100002 r /
t2
r | t | mhg | ac |
0.1825 | 89.67 | 0.80507 | 2.2401 |
0.2430 | 83.35 | 1.172668 | 3.4521 |
0.2610 | 82.61 | 1.282036 | 3.7746 |
0.2980 | 83.92 | 1.506848 | 4.1762 |
0.3425 | 80.38 | 1.77723 | 5.2319 |
Now, plot a graph between mhg (ON Y AXIS) and ac ( ON X AXIS)
Here is the graph
as we can see that
slope = 0.3329
therefore,
mass of the bob = 0.3329 Kg

PLEASE LET ME KNOW IF YOU HAVE ANY DOUBT. THERE IS NO MISTAKE IN THE METHOD.

please help. the last 2 have been incorrect and I only have one
more attempt!!

I dont have excel please help! It's asking
to calculate the acceleration, then calculate the mhg,
then graph them, and report the slope. The slope is the mass of
Bob.
