Acceleration, a = (v - u) / t
Initial Velocity, u = 30 m/s
Final Velocity, v = 23 m/s
time t = 2.00 seconds
a = (23 - 30) / 2
a = -7 / 2 = -3.5 m/s2
So the acceleration is negative, which means it is a deceleration of 3.5 m/s2.

Answer:
Atomic number of the daughter isotope = (Atomic number of the parent isotope) - 4
Explanation:
An alpha particle has atomic number of 2 and a mass number of 4
Losing two alpha particles would lead to a reduction of 4 in atomic number and 8 in mass number for the radioactive isotope, to give the stable daughter isotope.
