1. Compare and contrast Aristotle's and Galileo's views of: a. horizontal motion b. vertical motion C. projectile motion

You roll a ball across a level table and it reaches the edge. During its two-dimensional motion that begins as the ball rolls past the table's edge, which of the following quantities are zero? Select all that are 0 a. The vertical component of the balls initial velocity b.The horizontal component of the balls initial velocity c. The vertical component of the ball's acceleration d. The horizontal component of the balls acceleration

An object is  accelerating if it is moving __________________.  Select all that applies.  a. with changing speed b. extremely fast  c. with constant velocity d. in a circle e. downward f. none of these

Question part b I'm not sure how do we calculate
