<h2>
Person must have 8.18 m/s to catch the ball</h2>
Explanation:
Consider the vertical motion of ball
We have equation of motion s = ut + 0.5at²
Initial velocity, u = 12 m/s
Acceleration, a = -9.81 m/s²
Displacement, s = -25 m
Substituting
              -25 = 12 x t + 0.5 x -9.81 x t²
                4.905 t² -12t - 25 = 0
               t = 3.79 sec
Ball hits ground after 3.79 seconds.
So person need to cover 31 m in 3.79 seconds
Consider the horizontal motion of person
We have equation of motion s = ut + 0.5at²
Initial velocity, u = ?
Acceleration, a = 0 m/s²
Displacement, s = 31 m
Time, t = 3.79 seconds
Substituting
              31 = u x 3.79 + 0.5 x 0 x 3.71²
                u = 8.18 m/s
Person must have 8.18 m/s to catch the ball

 This brightly colored fish is native to the Indo-Pacific from Australia north to southern Japan and south to Micronesia.  The lionfish is usually found in coral reefs of tropical waters, hovering in caves or near crevices.  Native regions as well as Savannah, Georgia; Palm Beach and Boca Raton, Florida; Long Island, New York; Bermuda and possibly Charleston. In southern Florida and off the coast of the Carolinas in early to mid 1990s.

Answer:
Explanation:
Let v be the velocity acquired by electron in electric field 
V q = 1/2 m v²
V is potential difference applied on charge q , m is mass of charge , v is velocity acquired 
2400 x 1.6 x 10⁻¹⁹ = .5 x 9.1 x 10⁻³¹ x v²
v² = 844 x 10¹²
v = 29.05 x 10⁶ m /s 
Maximum force will be exerted on moving electron when it moves perpendicular to magnetic field . 
Maximum force = Bqv , where B is magnetic field , q is charge on electron and v is velocity of electron 
= 1.7 x 1.6 x 10⁻¹⁹ x 29.05 x 10⁶
= 79.02 x 10⁻¹³ N .
Minimum force will be zero when electron moves along the direction of magnetic field .
