Part A A solid, uniform ball rolls without slipping up a hill, as shown in the figure (Eigute 1). At the top of the hill, it is moving horizontally, and then it goes over the vertical dit. How far from the foot of the cliff does the ball land? Submit Request Answer Part B How fast is it moving just before it lands? Vol A£d O E) ? m/s Submit Bequest Anawer Part C Notice that when the bals lands, it has a greater translational speed than when it was at the bottom of the hill. Does this mean that the ball somehow gained energy? Explain!

Angular speed, acceleration and displacement

Angular acceleration is defined as the rate of change in angular velocity with respect to time. It has both magnitude and direction. So, it is a vector quantity.

Angular Position

Before diving into angular position, one should understand the basics of position and its importance along with usage in day-to-day life. When one talks of position, it’s always relative with respect to some other object. For example, position of earth with respect to sun, position of school with respect to house, etc. Angular position is the rotational analogue of linear position.
