Question

Hi have made an attempt to show that f=mv^2/R may be written as F=mw^2R using the following formulas
v=2piRn/delta t , w=2pin/delta t and w= Delta theta/ delta t..
however i was unsuccessful please help

Answer 1

Look at these two equations:
\[ v = \frac{2 \pi R n}{\Delta t} \]
\[ \omega = \frac{2 \pi n}{\Delta t} \]

Notice that *immediately* you can write
\[ v = \omega R \]

Answer 2

thank you so much !!!!!!!
