a kitten pushes a ball of yarn rolling toward it at 0.0600 m/s with its nose, moving the ball of yarn 0.475m in the opposite direction in 2.00s. what is the acceleration of the ball of yarn

Answer 1

Let the initial velocity of 0.06 m/s = v_i and the final velocity = .475/2 = v_f. Let the average acceleration be (vf-vi)/Δt=(.238-.06)/2 = .089 m/s²
