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

A child a rides a carousel at t = 0 and moves in a circle that is 8 m in circumference at a speed of constant modulus of 1m / s. determine:

a) the movement of t = 0s to t = 1s

b) the average speed from t = 0s to t = 3s

c) the average acceleration between 1s and 3s

2. Relevant equations

I've got these that i figure work:

v= v_{x}i+ v_{y}j

and

movement = Δxi+ Δyj

3. The attempt at a solution

Given that the correct answers(provided by my textbook) should be

a) (0,900i-0,372j)m

b) (0,300i- 0,724j)m/s

c) (-0,707i) m/s^{2}

I dont seem to know how to apply the equations above to land these answers... Vectors confuse me. For instance, Δx and Δy represent what ? I'm stuck. HELP!
