Question

weight of body is 550 N calculate mass​

Answer 1

Answer:

His "force of gravity" refers to his weight on earth. Weight=Force=ma=mg, where m is his mass and a is the acceleration due to gravity g. The acceleration of gravity on earth is 9.8 m/s^2. So his mass is Weight/gravity=500 N / 9.8 m/s^2 = 51 kg
