Question

A 100 kg bag of sand has a weight on 100 N When dropped its acceleration is what?

Answer 1

force=mass*acceleration
100N=100kg*acceleration
1 N/kg = acceleration

hope it helpsu

Answer 2

The acceleration = 1 m$s^{-2}$,

Explanation:

• The second law of Newton states that speed is directly proportional to force and inversely proportional to mass. Kinematic measurements allow for the definition of accelerations. Advanced physics has provided a thorough description of kinematics through reference frame analysis, yet there are still significant uncertainties over the correct definition of mass. Although general relativity provides an equivalency between space-time and mass, it is uncertain how or whether this link applies on microscales in the absence of a cogent theory of quantum gravity. By formulating the law as an equality, Newton's second law can be interpreted as a quantitative definition of mass with some reason; the relative units of force and mass are then fixed.
• According to the given information, it is given that,

A 100 kg bag of sand has a weight on 100 N. This means that the mass of the bag of sand that is m = 100 and the force exerted downwards that is

F =  100.

According to Newton's second law,

F = m * a , where a = acceleration of the bag of sand.

Then, we get,

a =

$\frac{F}{m} \\= \frac{100}{100} \\=1 ms^{-2}$

Thus, the acceleration = 1 m$s^{-2}$.
