Question

A ball rolls off a table (that is, it has a horizontal velocity) and then falls to the floor. Assuming that up is positive and the ball is initially moving horizontally in the positive x direction, match the following graphs with the correct desciption. [Choose ] The ball's vertical velocity (v-y) vs. time (t) The ball's vertical position (y) vs. time (t) The ball's vertical acceleration (a-y) vs. time (t). The ball's horizontal velocity (v-x) vs. time (t) The ball's horizontal position (x) vs. time (t) Choose ] Choose ]

Explanation / Answer

(a) The ball's vertical position (y) vs time (t).

(b) The ball's veriticle velocity (v-y) vs time (t).

(c)The ball's horizontal velocity (v-x) vs time (t)

(d) The ball's horizontal position (x) vs time (t).

(e) The ball's vertical acceleration(a-y) vs time (t).
