A basketball is thrown vertically up from a 1.6‑m height with an initial speed v0 = 23 m/s. At what speed will the ball hit the ground?

The speed of the ball, v1 =  

How long will it take for the ball to reach the ground?

The time of flight, t1 =  

Now the basketball is thrown vertically down from the same 1.6‑m height and with the same initial speed v0 = 23 m/s. First, check your physical intuition and complete the following two statements:

If the initial velocity is directed down, the final speed of the ball (Select an answer: decreases, increases, stays the same, do not know) .

If the initial velocity is directed down, the time of the free fall (Select an answer: decreases, stays the same, increases, do not know) .

Now, with the new conditions, what will be the speed of the ball just before it hits the ground?

The speed of the ball, v2 =  

How long will it take for the ball to reach the ground?

The time of flight, t2 =
