Calculating Rotation Rate for a Diver Jumping from 13m High Tower

AI Thread Summary
To calculate the rotation rate for a diver jumping from a 13m high tower, the time of the fall is determined using the equation t = √(2h/g), resulting in approximately 1.628 seconds. The diver aims to complete 212 somersaults, which translates to a rotation in radians that must be calculated for accuracy. The initial calculation of rotation rate as 1.53 revolutions per second was incorrect due to not converting the rotations to radians. After correcting the approach, the correct rotation rate can be found by dividing the total radians by the time of the fall. The discussion highlights the importance of using the correct unit conversions in rotational motion calculations.

Homework Statement





A diver jumps from a 13m high tower, and hopes to complete 212 somersaults.
what should be the rotation rate be

Homework Equations





The Attempt at a Solution



13 m = (1/2)(9.81 m/s²)(t²)
t = 1.628 s

ω = 2.5 rev / 1.628 s
ω = 1.53 rev/s I'm still getting this wrong

Am I not using the correct equation for time?

What is the problem ?
 
Please post the problem statement so we can figure out what it is you're trying to figure out!
 
sorry sorry! now it is there
 
Ugh...Nevermind i figured it out. I needed ot find the Rotation in radians and divided it by the time.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
