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!

Can you calculate the initial speed from speed-time graph?
Yes.
What is the height of a rock that is thrown upward with an initial speed of 15 meter per second?
We have no idea how big the rock is, and no way to figure it out. But we can calculate that it reaches 11.48 meters above the ground before it starts falling.
The speed of a baseball crossing home plate after being pitched depends on its initial velocity. If thrown at 74 mph the speed over home plate will be 72.2 mph. If thrown at 50 mph the speed over home?
Speed(74) = 72.2Speed(50) = 44.7
How do you calculate speed without distance?
If you know the initial speed (u), acceleration (a) and time (t), then the final speed, v = u + at.
True or false To calculate the acceleration of and automobile you must first subtract the final speed from the initial speed?
True
Will two free fall bodies with different initial speeds reach ground together?
No. The one with higher initial speed will hit the ground first if they are both thrown straight down.
Can you calculate the initial speed from speed-time graph?
Yes.
A projectile is thrown with an initial velocity which has a horizontal component of 4 m s What will be its horizontal speed after 3s?
A projectile that is thrown with an initial velocity,that has a horizontal component of 4 m/s, its horizontal speed after 3s will still be 4m/s.
How do you answer this physics question?
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?
A stone is thrown straight upward and it rises to a height of 20 meters With what speed was it thrown?
6.261 m/s
How do you calculate initial speed without time given?
distance divided by speed is equal to timetraveled.
What is the height of a rock that is thrown upward with an initial speed of 15 meter per second?
We have no idea how big the rock is, and no way to figure it out. But we can calculate that it reaches 11.48 meters above the ground before it starts falling.
A ball is thrown straight up At the top of its path its instantaneous speed is?
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.
The speed of a baseball crossing home plate after being pitched depends on its initial velocity. If thrown at 74 mph the speed over home plate will be 72.2 mph. If thrown at 50 mph the speed over home?
Speed(74) = 72.2Speed(50) = 44.7

The speed of a baseball crossing home plate after being pitched depends on its initial velocity If thrown at 74 mph. the speed over home plate will be 72.2 mph If thrown at 50 mph. the speed over ho?
Speed(74) = 72.2Speed(50) = 44.7
