A block is on a surface with us=0.276. It takes 1.11 N to break it free from static friction. What is the mass of the block?

m = 0.409 [kg].

Explanation:

The friction force is defined as the product of the coefficient of friction by the normal force. In this way, we have the following equation.

F = μ*N

Where:

F = friction force = 1.11 [N]

μ = static coefficient = 0.276

N = Normal force [N]

We can clear the normal Force.

And the normal force of a body lying on a horizontal surface, can be calculated by means of the product of mass by gravitational acceleration.

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
