p = m*v
Assuming earth gravity (9.81m/s²)
m = W / g = 552 / 9.81 = 56.27kg
p = 56.27*1.22 = 68.65 kg.m/s (to 2 dp)
Your weight is ma where a is the acceleration due to gravity.
Take your weight and divide it by 9.8 then multiply you now mass by 1.22 which is you velocity.
therefore you have (552/9.8)x1.22= momentum
