Answer:
3.79 m/s²
Explanation:
Given that:
The mass of refrigerator = 120 kg
The height of refrigerator = 2.20 m
The width of refrigerator = 85.0 cm = 0.85 m
Since the center of gravity is located at the geometrical center.
Then;
the center mass of refrigerator = h/2 = 2.20 m / 2
= 1.10 m
From width of refrigerator, the distance of center mass to either edge of refrigerator = 0.85 m / 2
= 0.425 m
So; the torque acting on the center mass due to the force F is:
the torque acting on the center mass due to the weight of the refrigerator is:
Thus, since the refrigerator does not tip over,
F(1.10 m) = w(0.425 m)
ma (1.10 m) = mg (0.425 m)
a (1.10 m) = g(0.425 m)
a = 3.79 m/s²
Answer:
Force has a direct relationship to mass and acceleration. Newton's Second Law, force equals mass times acceleration (F=MA), illustrates their general relationship in an equation.
Explanation:
Relationships to remember:
- <u>Force</u> and <u>acceleration</u> have a direct relationship, meaning if force increases, acceleration will also increase and vice versa
(Ex: The harder you push a box, the faster it will move)
- <u>Mass</u> and <u>acceleration</u> have an inverse relationship, meaning if mass increases, acceleration will <em>decrease</em> and vice versa
(Ex: If you add more furniture in the back of a moving company truck, the truck will move slower than it did before the furniture was added)
- <u>Force</u> and <u>mass</u> have a direct relationship, meaning if mass increases, force will also increase
(Ex: You will need to exert less force to lift a 5-pound weight than a 10-pound weight)
And of course, Newton's Second Law, F=MA sums all of this up in 3 letters and a symbol! If you have any more questions about this problem, please comment on my answer :)
