Answer 2

2nd law:rate of change of momentum is directly proportional to the force applied
Initial momentum:P1
Initial momentum:P2
P1+P2/t is directly proportional to F
P=mv
mv+mu/t is directly proportional to F
m(v-u/t) is directly proportional to F
ma is directly proportional to F
F=kma
k=1(proportional constant)
F=ma
