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= vxi + vyj 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/s2 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!
