Acceleration of gravity is 9.8 m/s
Ball continues to rise for (50/9.8) seconds. Then its speed is zero before it starts to fall.
During the ascent, average speed is 1/2 (50 + 0) = 25 m/s.
Distance straight up = (average speed) x (time of ascent) = 25 x (50/9.8) = 127.55 meters (rounded).
This is one heck of a toss ! Almost 420 feet up ... like the height of a 40-story building ... before it starts to fall.
But 50 meters per second is a launch at 109 mph ( ! ), so I guess I'll stand by my math. Note that as always, air resistance has been ignored.
Its initial speed cannot be 20 m, as stated in the question. Secondly, if the initial speed is correctly given, then there is no need to calculate it!
The initial velocity is zero. In most basic physics problems like this one the initial velocity will be zero as a rule of thumb: the initial velocity is always zero, unless otherwise stated, or this is what you are solving for Cases where the initial velocity is not zero examples a cannon ball is shot out of a cannon at 50 mph a ball is thrown from at a speed of 15 mph etc
That depends on whether you mean a golf ball, or something large and light like a volleyball,which is more venerable to air resistance, and would have to have a higher initial speed to reach 60m.
... and what is the question? The second ball should arrive at the floor a second after the first, both should have the same speed.
They should reach the ground together, since their initial vertical speed is the same, namely zero.

A ball is thrown vertically upward with an initial speed of 20m/s. Two second later, a stone is thrown vertically (from the same initial height as the ball) with an initial speed of 24m/s. At what height above the release point will the ball and stone pass each other?

If a ball is thrown horizontally from a window on the second floor of a building, the vertical component of its initial velocity is zero.
If it is thrown at an angle, at the top of its path, its vertical velocity will be zero, however its horizontal velocity will be the same as its initial horizontal velocity minus whatever loss in speed as a result of air friction at that point. We won't know what that is without more information.
After being released, a ball thrown straight down from a bridge would have an acceleration of
A the highest point its velocity will be zero.
The acceleration is the acceleration of gravity, downwards, or 9.8m/s/s (32 ft/s/s). When ball is thrown straight up it has an initial velocity that is decreasing because of gravity; at the highest point velocity is zero but acceleration is always constant at gravity rate.

If a ball is thrown, the force pushing the ball will convert to energy to speed up the ball.
A ball thrown down. The thrown ball will have a greater initial velocity and since they experience the same force of gravity, it will always be faster (until they both reach terminal velocity).
