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

Click For Summary

Homework Help Overview

The problem involves a diver jumping from a height of 13 meters and aims to determine the necessary rotation rate to complete 212 somersaults during the dive.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to calculate the time of the dive using the equation for free fall and questions whether they are using the correct equation for time. Other participants inquire about the problem statement to clarify the original poster's intent.

Discussion Status

The discussion includes attempts to clarify the problem and the original poster's realization about needing to convert rotations to radians for their calculations. There is no explicit consensus on the approach, but some guidance has been offered regarding the conversion of units.

Contextual Notes

There may be constraints related to the specific equations or methods allowed in the homework context, as indicated by the original poster's uncertainty about the equations used.

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.
