. where radius of the Earth is 6400km
But I can't get the ans=1.41hrs
I can only get 84.3hrs
square root of{Rg}=square root of (6400km X 35.3km/h)= 475
(R multiply by 2pie)divide by T= 40212/T
cross multiply them and I get 84.3hrs. Do u know where is the error?
1. Homework Statement
By considering the centripetal force acting on a man, calculate the minimum period of rotation that the Earth would need to have about its axis if a man at the equator were to experience zero normal contact force.
Take radius of Earth=6400km
2. The attempt at a...
The velocity decreases because at it comes near the top of the circle, the radius(of the verticle circle)decreases and since angular velocity is constant and depends only on the time it takes for one revolution. Thx! ^_^ Lol sry 4 the equation mistake.
Homework Statement
Can a pendulum that swings in a vertical circle have a constant speed throughout its motion?
How can I explain this phenomenon using angular velocity? Is there any instance when such case happen?
Homework Equations
1/2mv2 = mgh
velocity= radius X angular velocity...
