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.
A.The ball's horizontal position (x) vs. time (t).
B
The ball's vertical position (y) vs. time (t).
C
The ball's vertical velocity (vy) vs. time (t).
D
The ball's vertical acceleration (ay) vs. time (t).
E
The ball's horizontal velocity (vx) vs. time (t).
1.Exponential Fall
2. Linear Fall
3. Constant Positive
4. Linear Rise
5. Constant Negative
