the block is sitting at rest on teh floor . The normal force on the block is 3.00 N find the mass of the block
1 answer:
Answer:
m = 0.305 [kg]
Explanation:
When a body rests on a horizontal surface and is in balance we can say that normal force is the reaction of the weight of a body.
Weight is defined as the product of mass by gravitational acceleration.

where:
N = normal force = 3 [N]
g = gravity acceleration = 9.81 [m/s²]
m = mass [kg]
Now replacing:
![3=m*9.81\\m=0.305[kg]](https://tex.z-dn.net/?f=3%3Dm%2A9.81%5C%5Cm%3D0.305%5Bkg%5D)
