because the total mass is 3kg, the 2kg block has a 1kg block on top. so if i pull with 20N i have to take into account the top block an additional 1kgharuspex said:
Which system did you compute the forces on? What is the total mass of that system?isukatphysics69 said:
hey i figured that problem out, do you understand ranking forces?Orodruin said:
That last attempt is clearly wrong since you have FFBA > ... FFBA.isukatphysics69 said:
The formula for finding acceleration between two blocks is a = (m2 – m1)g / (m2 + m1), where a is the acceleration, m2 is the mass of the top block, m1 is the mass of the bottom block, and g is the acceleration due to gravity (9.8 m/s²).
To determine the mass of the blocks, you will need to measure their weight using a scale. Then, divide the weight by the acceleration due to gravity (9.8 m/s²) to calculate the mass in kilograms (kg).
Yes, this formula can be used when the blocks have different masses. Simply plug in the mass values for each block in the formula: a = (m2 – m1)g / (m2 + m1).
Finding the acceleration between two blocks can help us understand the forces acting on the blocks and how they are moving in relation to each other. It can also be used to calculate the net force acting on the blocks.
While this formula is commonly used for calculating acceleration between two blocks, it can also be applied to other objects as long as their masses and the acceleration due to gravity are known.
