Answer:
a) 980 N
b) 100 kg
c) 163.33 N
Explanation:
a)
The weight of the object on Earth is the product of its mass times the acceleration due to gravity, that is:
b)
The mass of the object on the moon, is exactly the same (100 kg) since mass is an inherited value of the object.
c)
Considering that the acceleration of gravity on the Moon is about 1/6 that we have on earth (g), then the weight of the object on the Moon becomes:
Explanation:
Here,
Given,
Mass(m)=40 kg
Gram=9.8m/s
Now,
Weight=m x g
or, weight= 40x9.8
=392.0

I attached a Diagram for this problem.
We star considering the system is in equlibrium, so
Fm makes 
with vertical
Fm makes 70 with vertical
Applying summatory in X we have,
We know that W is equal to
Substituting,
<em>For the second part we know that the reaction force Fj on deltoid Muscle is equal to Fm, We can assume also that</em>
