Calories and joules are two different measurements of amounts of energy.
Arsenic is Element Number 33 ... it has 33 protons in its nucleus.
You're correct that the stable isotope of the atom is the one with
42 neutrons, for a total Atomic Weight of 75.
Atoms of Arsenic also exist with 41 neutrons and 40 neutrons
in their nucleus, but those are unstable.
The nucleus with 41 neutrons (Atomic Weight = 74) has a 50% chance
of falling apart and becoming a nucleus of Germanium within 80 days.
The nucleus with 40 neutrons (Atomic Weight = 73) has a 50% chance
of falling apart and becoming a nucleus of Germanium within 18 days.

Answer:
K_A = 32.2 10⁶ J
Explanation:
In this exercise we must relate the quantities given to find the kinetic energy
Asteroid A data
m_A = 3.5 m_B
v_A = 2.0 v
they also give the value of the kinetic energy of asteroid A
K_B = 2.3 10⁶ J
the expression for scientific energy is
K = ½ m v²
let's replace
K_A = ½ m_a V_a2
K_A = ½ 3.5 m_B (2.0 v_B)^2
K_A = 3.5 2² (½ m_B v_B²)
K_A = 14 K_B
K_A = 32.2 10⁶ J
