in this type of reaction , two ionic compounds react and swaps their cations or anions giving two new compounds in the product. hence the double replacement reactions does not deal with the nucleus. all other terms like strong nuclear forces, radioactivity and nuclear decay deal with the nucleus.
Answer:
Average force is F = mass times change in V/ change in time so..
1 366.07143 N
Explanation:
51 kg x 15 m/s / 0.56
1 366.07143 m kg / s
1 366.07143 N
1 kilogram 1 meter per second per second = 1 N
