Part 2) A ball undergoes uniform circular motion in a horizontal plane in an anti-clockwise direction. It traces out a path with a radius of r = 1.07 m over a period T = 2.20 s. Calculate the speed of the ball. U = 3.06 m/s Your last answer was interpreted as follows: 3.06 Part 3) Consider the ball undergoing uniform circular motion as described in Part 2 at the points shown below. i is a unit vector in the x direction and j is a unit vector in the y direction. Write the acceleration of the object at points A and B in unit vector notation. A CO aA = it j m/s 2 aB = it i m/s2
