What is approximately 48m/s?
The greatest final speed when hitting the ground out of three balls launched from the same height would be: ball 1, thrown horizontally at speed v; ball 2 thrown at 45 degrees to the horizontal at speed v; ball 3 thrown at 60 degrees to horizontal at speed v

The linear speed due to Earth's rotation for a person located at a latitude of 32 degrees
r=6.4x10^6
What is 395m/s?
The height by which a golf ball clears a wall when it is hit by a club with a speed of 75m/s and an angle of 50° above the horizontal with 12-meter-high wall is located at a horizontal distance of 265m from the place where the ball was struck

What is jerk?
The direction and relative velocity of a plane heading 600m/s due north while encountering winds of 200m/s east, relative to the ground
The total displacement when an object moves straight with an initial speed of 24m/s, decelerates at 4 m/s² until its velocity is half of what it was, then immediately accelerates uniformly at 5 m/s² until it returns to its original velocity
What is 97.2 meters
