Derive the mathematical form of second law of motion. A force of 5 N produces an acceleration of 8 m s-²on a mass m1 and an acceleration of24 m s2 on a mass m2. What acceleration wouldthe same force provide if both the masses are tiedtogether? |

Answer» AnswerFrom Newton's second law of motion, the APPLIED force is directly proportional to the acceleration produced or F=maThe unit of force is newton in SI DENOTED by the symbol N.Forces acting on a mass m 1 with acceleration a 1 and mass m 2 with acceleration a 2 are as GIVEN below.m 1 = a 1 F = 85 kg.m 2 = a 2 F = 245 kg.M=( 85 + 245 )kg=( 65 )kgAcceleration produced in M (when the two masses are tied TOGETHER),a= MF = 65 5 =6 ms −2 |
