According to the concept of length contraction, what happens to the length of an object as it approaches the speed of light and
lord [1]
When an object moves its length contracts in the direction of motion. The faster it moves the shorter it gets in the direction of motion.
The object in this question moves and then stops moving. So it's length first contracts and then expands to its original length when the motion stops.
The speed doesn't have to be anywhere near the speed of light. When the object moves its length contracts no matter how fast or slow it's moving.

A ball is revolving horizontally in a circle of radius 1.8 m, and is held by a rigid, massless rod. The mass of the ball is 0.1
OLga [1]

Answer:

 \omega=15 \ rad/s

Explanation:

given,

radius of circle = 1.8 m

mass of the ball = 0.1 Kg

linear speed of the ball = 27 m/s

angular velocity of orbit = ?

 v =  r \omega      

ω is the angular speed of the circle

 \omega=\dfrac{v}{r}      

 \omega=\dfrac{27}{1.8}        

 \omega=15 \ rad/s              

the angular velocity of the orbit is \omega=15 \ rad/s
