Answer:

if you are asking for static friction the answer is  <u>372N</u>

Explanation

friction static=normal force x coefficient of static friction

and normal force is equal to weight of a body

so  static friction = 600N x 0.62= 372N

A sample of the material halite measures 3.18 cm long by 3.06 cm wide by 2.79 cm high and has a mass of 58.75 g. What is the its
tatiyna
Specific gravity = Density of an object/Density of water

Density = Mass/Volume

For the current scenario;

Density of halite = mass/(l*w*h) = 58.75/(3.18*3.06*2.79) = 58.75/27.148932 = 2.164 g/cm^3

Density of water ≈ 1000 kg/m^3 = 1 g/cm^3

Therefore,
Specific density of halite = 2.164 g/cm^3 / 1 g/cm^3 = 2.164

What is the mass of a cart that accelerates at 3.0 m/s if a 0.5 N force is applied?
frozen [14]

The mass of the cart is 0.167 kg

Explanation:

We can solve the problem by using Newton's second law, which states that the net force applied to an object is equal to the product between its mass and its acceleration:

F=ma

where

F is the net force acting on an object

m is its mass

a is its acceleration

For the cart in this problem, we have

F = 0.5 N is the net force applied

a=3.0 m/s^2 is the acceleration

Substituting, we find the mass:

m=\frac{F}{a}=\frac{0.5}{3.0}=0.167 kg

Find the magnitude of the side and the angle. Please help!
-BARSIC- [3]

Answer:

Explanation:

<em>Assuming the triangle is a right triangle,</em>

the magnitude of R can be found using the Pythagorean theorem,

R = sqrt(9.7^2+6^2) = 11.41 m

The angle can be found by arctangent, which is

angle = atan(9.7/6) = 58.26 degrees.

Eric has a mass of 80 kgkg. He is standing on a scale in an elevator that is accelerating downward at 1.7 m/s2m/s2. What is the
kolezko [41]

Answer:

The answer will be 936 N.

Explanation:

Given that

m = 80 kg

Acceleration of the elevator , a= 1.7 m/s²  ( upward)

The gravity force on the mass = m g

The reading on the scale = F N

Now by applying the Newton's second law

F - m g = ma

F= m g + m a

F= m ( g +a )

F= 80 ( 10 + 1.7 ) N                                  ( take g= 10 m/s²)

F=80 x 11.7 N

F= 936 N

Therefore the reading on the scale will be 936 N.

The answer will be 936 N.
