(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A1. An object undergoing circular motion is pictured below at time t = 0 s.

(a) What is the angular frequency of the object?

(b) What is the equation of the displacement of the object in the x-direction?

(c) What is the equation of the displacement of the object in the y-direction?

(d) What is the y-displacement of the object at t = 0 s?

(e) What is the ﬁrst time after t = 0 s that y = 0?

I cant put the diagram on here but its a circle on x/y axis with the object in the lower right quadrant where θ=45° and v=2m/s and the r=2m

2. Relevant equations

T=2∏r/v

ω=2∏/T

x=Acos(ωT+δ)

3. The attempt at a solution

Ive managed to do part (a) using the equations above and got 1rad/s

However im not sure on the rest, i was thinking of using x=Acos(ωT+δ) but im not sure how

cheers for any advice
