Answer:
F = 49,56 Kgs
Step-by-step explanation:
We Know that 113 calories = 4186 J
Joules ( energy unit in MKS system meter, kilograms , second)
and 2,51 % of 4186 is 0,0251 * 4186 = 105.07 J
That the energy available
Work is W = F * d
where F is the force you have to apply and d is traveled distance
in this case F is the weight of the barbell
Then
F = W / d ⇒ F = 105.7 / 2.12 ⇒ F = 49,56 Kgs
