What is a, where is the acceleration that a body of mass m = 11 tons acquires under the action of a force F = 60 kN?

It is necessary to convert units to the SI system
1 kN = 1000 N, therefore 60 kN = 60,000 N
1 t = 1000 kg, therefore 11 t = 11000 kg
According to Newton’s second law F = ma, we express a, it turns out a = F / m
Substitute the numbers. a = 60000/11000 = 5.45 N.
Answer: 5.45Н
