Answer:
0.215
Explanation:
by using the equations of the constant acceleration motion or uniformly accelerated rectilinear motion:
V= + a⋅t
X=+ *t +
in this case = 0, = 2.5 and X= 14.5.
replacing those numbers in the equations,and knowing that a gravitational acceleration is always negative :
1. V= 2.5 - a⋅t
2. 14.5=2.5 *t -
we have 2 unknowns (g and t) ,so this can be solve by the Substitution Method :
0= 2.5 - a⋅t
V in this case will be 0,because the speed at the maximum distance is 0.
by solving for a:
3. a=
and replacing in 2. :
14.5=2.5 *t -
14.5=2.5 *t -
14.5=
by solving for t:
t =
t= 11.6 s
with this value of t,replacing in 3. :
a=
a= 0.215
Hello!
By applying the third law of motion, your force and the wall's force are equal.
I hope this helps you! Have a great day!

The mass number is calculated by adding the number of protons and the number of neutrons.
Therefore, you can find the number of neutrons by subtracting the number of protons from the mass number. The number of protons is equal to the atomic number, therefore you just have to do the mass number - atomic number to find the number of neutrons.
82 - 26 = 56 neutrons.
