Answer:
2(a). 50.99 kg
(b) 81.58 N
(c) 312.50 kg
3(a). 9800 N
(b) 0.02943 N (in this case you will have to convert milligrams to kilograms)
4. (gravitational force and tension will be the same here)
Weight = 490.33 N
Gravitational Pull = 9.81 N/kg
Step-by-step explanation:
Here is a very simple way to figure out what formula to use for weight, mass, and gravitational strength.
To use the triangle, cover up the variable you are trying to find and then the triangle will tell you the formula. So,
Weight = Mass x gravitational strength
(or just gravity whatever you are more familiar with)
Mass = Weight ÷ gravitational pull/gravity
Gravity = Weight ÷ Mass
In this case though, 1 kg = 9.81 N which is what you are looking for in this worksheet.
