The mass of the body is 832 Kg.
The mass of a body could be obtained from the second law of motion as propounded by Newton. We know that; F = ma
F = force
m = mass
a = acceleration.
Given that the rate of change of momentum is directly proportional to the impressed force;
F = 54,080 N
a = 65 m/s2
m = F/a
m = 54,080 N/ 65 m/s2
m = 832 Kg
