The answer is definitely letter C. They are both located in the nucleus. Their summation define the mass of one (1) atomic mass unit of a particular element. For example, for carbon atom it has 6 protons and 6 neutrons. Therefore the atomic mass of carbon is 12.
We have that the instantaneous power is

From the question we are told that
A 60 kg person runs up a 30° ramp
distance of 15 m up the ramp in 5.8 s.
t = 4.0 s?

Answer:
a) F = 1.26 10⁵ N, b) F = 2.44 10³ N, c) F_net = 1.82 10³ N directed vertically upwards
Explanation:
For this exercise we must use the relationship between momentum and momentum
I = Δp
F t = p_f -p₀
a) It asks to find the force
as the man stops the final velocity is zero
F = 0 - p₀ / t
the speed is directed downwards which is why it is negative, therefore the result is positive
F = m v₀ / t
F = 63.5 7.89 / 3.99 10⁻³
F = 1.26 10⁵ N
b) in this case flex the knees giving a time of t = 0.205 s
F = 63.5 7.89 / 0.205
F = 2.44 10³ N
c) The net force is
F_net = Sum F
F_net = F - W
F_net = F - mg
let's calculate
F_net = 2.44 10³ - 63.5 9.8
F_net = 1.82 10³ N
since it is positive it is directed vertically upwards
There's no "control" they all differ. If they were all exactly the same size shape and material it would be doable.
