Answer:
a cold air mass and a warm air mass merge together
Hm pretty much that's all for alpha decay... But always after any alpha or beta decay, gamma photons are released because the daughter products end up in an excited state so they have to release energy through gamma decay
As we know that acceleration is given as

here we know that



now we will have


so acceleration will be 3 m/s^2
