Question

Derive the formula
v=rw​

Answer 1

Answer :

The study of angles and of the angular relationships of planar and three-dimensional figures is known as trigonometry.

Answer 2

Answer:

Circle of radius r,

Time for one circular motion  t

Angular speed is w= 2π/t

Tangential velocity=v =2πr/t

this gives               v= (2π/)*r

                             =wr
