A ball is going through freefall. It is thrown up into the air. What is the velocity of the ball when it reaches its maximum height?
0m/s
A ball is thrown up in the air. It takes 3 seconds to reach its peak. What was its INITIAL VELOCITY
29.4m/s

How do you find displacement on a Velocity vs Time graph?
Take the area underneath the curve
A ball is thrown up into the air and undergoes freefall. Gravity accelerates the ball downwards. When the ball is at its peak, what is the acceleration due to gravity? What is its sign?
-9.8m/s2

What does a horizontal line mean on a Velocity vs Time graph
Constant Velocity
a = 0m/s2
You dropped a ball from an INFINITE height, still affected by earth's gravity constant. There happens to be no air resistance. After an infinite amount of time, what happens to the velocity?
velocity = infinity
A ball is thrown up into the air at a speed of 12,008meters/hour and comes back down to the starting position. What was its hang time IN SECONDS

You are looking at a position vs time graph for a ball's movement. The graph went down 3m and over 2s. What is the velocity of the ball?
-1.5m/s
If you throw a ball into the air (positive velocity), but a negative acceleration, what happens to the velocity after a VERY LONG amount of time?
you will have a negative velocity
you will be speeding up in the negative direction
