Answer #1

We have equation of motion

v2 = u + 2as

Here u = 0, v= 237 m/s, S = 0.66 m;

Hence acceleration of bullet,

  ​​ a = U2 2372 252 x 0.66 = 42552.3m/s2

Force of action = Force of reaction

ՀՈՂbab = Դոն ԺԱq

Ag = mga/mg = 6.45 x 10-3 x 42552.3/4.5 = 61m/s2

Hope the answer and explanation helps you. All the best wishes for your studies ?
