Hope this helped you- have a good day bro cya)
Hope this helps, have a nice day ahead!
1-They will form the weakest bond.
2-The energy between them begins to decrease as they get closer, and it reaches the minimum when the two atoms are at an optimum distance apart.
3-But once the two atoms forced closer together, So the energy rapidly increases
P = m*v
p = momentum
m = mass
v = velocity
p = (37 kg + 18 kg)*(1.2 m/s)
p = (55 kg)*(1.2 m/s)
p = 66 kg-m / s
