A block with mass M is placed on an inclined plane with slope angle q and is connected to a second hanging block with mass m by
tensa zangetsu [6.8K]

Answer:

The mass of the block m is:

m=M(sin(\theta)+\mu_{s}cos(\theta))

Explanation:

Let's analyze the block by parts

For the block M

T-W_{x}-f_{f}=0 (1)

Where:

  • T is the tension
  • W(x) is the component of the weight in the x-direction
  • F(f) is the friction force

T-Mgsin(\theta)-\mu_{s}N=0  

T-Mgsin(\theta)-\mu_{s}Mgcos(\theta)=0  

For the block m

T-W=0

T=mg (2)

Now, let's combines equation (1) and (2):

mg-Mgsin(\theta)-\mu_{s}Mgcos(\theta)=0  

Finally, let's solve it for block m.

mg-Mg(sin(\theta)+\mu_{s}cos(\theta))=0

m=M(sin(\theta)+\mu_{s}cos(\theta))

I hope it helps you!

Why does a bouncing ball rise to a lower height with each bounce? What energy conversion is taking place?
dsp73
<span>So we want to know why the does a bouncing ball rise to a lower height with each bounce. So lets say the ball is first on some height h. There it has potential energy Ep=m*g*h. Then as the ball starts falling to the ground the energy converts to kinetic energy Ek=(1/2)*m*v^2. When the ball falls to the ground, the kinetic energy transforms to elastic energy because the ball deforms as it hits the ground and some small quantity of heat. The heat goes to the air and to the ground so it gets removed from the system. So there is less energy in the system to be converted back to kinetic energy as the ball starts to rise in height again. Thats why the ball is not able to get bact to the same height as it started from. </span>

If hydrogen and helium are the most abundant elements in the unoverse , then why are living organisms composed primarily of carb
Mumz [18]

Answer:

Most of materia isnt life.

Explanation:

The living organisms (life) aren't the most abundant thing in universe.

Hydrogen and helium are present in everywhere, but life isn't.

There is no reason to think because we have a lot of a thing, the life must be made for this thing.

The organic life just can exists because some mysterious properties about carbon, that is the basic foundation of life, carbon is a special element, why? We don't know, actually, it's a huge problem for science discover why the carbon can makes life be possible and other elements can't. But we know is this element that makes life possible.

So, note there isn't relation about the quantity of a material in Universe and the life constituition. In addition, look around, organic materials are very rare in Universe, Earth is one in lots of places and in most of this places there isn't sign of life.

Even in Earth the life looks abundant, in Universe it isn't, the same way in Universe the Hydrogen and Helium are abudant, in Earth isn't soo.
