How Fast Must a Golf Ball Travel to Avoid a Rotating Windmill Blade?

AI Thread Summary
To determine the minimum speed a golf ball must travel to avoid being hit by a rotating windmill blade, the problem involves calculating the time it takes for the blade to reach the position of the ball. Given that the windmill has 8 blades rotating at 1.25 radians per second, the time between successive blades passing a point is crucial. The diameter of the golf ball is 0.045 meters, and since no additional measurements for the windmill are provided, the focus remains on the angular speed and the ball's diameter. The solution requires understanding the relationship between the angular velocity of the blades and the linear speed of the ball. The discussion emphasizes the need for clarity on the problem's parameters to find the correct answer.

please I need help on rotational velocity problem for tomorow dec 7

ok i need help on where to begin this problem because i am lost. any help would be appreciated thank you

A windmil has 8 blades and rotates at an angular speed of 1.25 radians/second. the opening between succesive blades is equal to the width of of a blade. a golf ball of diameter 4.50*10 -2m is just passing by one of the rotating blades. what is the minimum speed of the ball so that it will not be hit by the next blade?

thnk you for your time

hmm - is that all the info u r given?
 
yes that is all we are given
 
what about the measurements of the windmill?
 
no measurments given
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'A bead-mass oscillatory system problem'

I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
