An object of mass 1.00kg is moving over a horizontal circular path of radius 2.00m, with a speed of 3.00ms^-1. Determine:

Question

(a) its centripetal acceleration

(b) its kinetic energy

(c) its period

(d) its angular velocity

Answer 1

(a) Av = v^2/r = 9/2

(b) (1/2) m v^2

(c) distance = 2 pi r
time = distance / v

(d) omega = v/r

Hey, this is all in your text easy.

Answer 2

What do you mean? Please help, i'm still confused

Answer 3

google centripetal acceleration

for example
