Answer:
1.241 kg
Explanation:
The mass of the man in kg is 195 pound * (1/2.2) kg/pound = 195/2.2 = 88.64 kg
If 1.4% of the mass of a human body is calcium, then the mass of calcium inside the 88.64 kg man is
1.4% * 88.64 = 88.64*1.4/100 = 1.241 kg
So there's 1.241 kg of calcium inside a 195-pound man

Answer:
maximum force (in N) can you exert horizontally on the crate without moving it = 564.075 N
Explanation:
Given data:
mass m= 115 kg
coefficient of friction μ =0.5
according to newton law of motion the net force acted on body is given by

here the body is in rest ,

N= it is the normal reaction force
N= mg = 115×9.81
therefore,
