Question

Derive the formula V=rw​

Answer 1

Answer:

Explanation:

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

Answer 2

where v is the tangential velocity, w is the rotational velocity, and r i the radius vector? From the attached image, it can be concluded that (each quantity is a vector): w=r x v, also v=w x r, and r= v x w. ... w=rv, v=wr, r=vw, this system of equations is true if w=v=r which mustn't ...
