Homework Statement
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
Homework Equations
I've got these that i figure work:
v= vxi + vyj
and
movement = Δxi + Δyj
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/s2
I don't 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!
