Question

ii) An object of mass 50 g moves uniformly along a circular orbit with an angular speed of 5 rad/s.

If the linear speed of the particle is 25 m/s, what is the radius of the circle? Calculate the centripetal force​

Answer 1

Answer:

r = 5m

Step-by-step explanation:

Given:

m = 50g

ω = 5 rad/s

v = 25 m/s

Centripetal Force = $\frac{mv^2}{r}$ or mω²r

Therefore CF = $\frac{mv^2}{r}$ = mω²r

CF = v² = ω²r²

v = ωr

25 = 5r

r = 5 m
