Prove f=ma?

1.	Prove f=ma?
Answer» Force directly proportional to the rate of change of momentum. F=mv-mu/tF=m(v-u)/t(V-u)/t=aF=ma?? f=m×(v-u/t)(v-u/t)=a (acceleration)so,f=m×af=ma,proved By Newton second law of motion - F=change of momentum /time taken So momentum is mv Thus, f is proportional to m v-u/t (v-u/t) is acceleration So f is proportional to ma , F = kma (K is the value of proportion) =1Hence, f = ma
