Answer:
The value is
Explanation:
From the question we are told that
The potential of the proton is
Generally the momentum of the particle is mathematically represented as
Here e is the charge on the proton with value
m is the mass of the proton with value
So
=>
So the de-Broglie wavelength isis mathematically represented as
Here h is the Planck's constant with value
=>
=>
The shot has a constant downward acceleration of . Since acceleration is constant, the velocity of the ball is given by
where is the shot's vertical velocity at time
and
is its initial vertical velocity. We're given that
. So
gives the shot's velocity at time .
Because acceleration is constant, we also know that
where is the average vertical velocity,
is the vertical displacement at time
, and
is the initial displacement at
. We're given an initial displacement of
, so the displacement of the shot is
The shotputter is 1.90 m tall, a difference of 0.20 m from the initial height of the throw. So we want to find the time for the ball to reach a displacment of -0.20 m:
