Emma is working in a shoe test lab measuring the coefficient of friction for tennis shoes on a variety of surfaces. The shoes ar

Rashid [163]

Answer:

Explanation:

Force of friction = μ N , where μ is coefficient of friction , N is normal force on the body .

a )

Given,

Normal force N = 400 N

Force of friction = 300 N

μ = coefficient of static friction = ?

Putting the values ,

300 = 400 μ

μ = .75

b )

Normal force N = 400 N

Force of friction = 200 N

μ = coefficient of kinetic friction = ?

Putting the values ,

200 = 400 μ

μ = .50

c ) see attached file .

If a spring constant of 128N/m is compressed by 0.18 m , how much potential energy is the spring?

Mademuasel [1]

Answer:

2.1J

Explanation:

Given parameters:

Spring constant = 128N/m

Compression = 0.18m

Unknown:

Potential energy of the spring = ?

Solution

The potential energy of the spring is the elastic potential energy within the spring.

To solve this;

Elastic potential energy = $\frac{1}{2}$ k e²

k is the spring constant

e is the compression

Now;

Elastic potential energy = $\frac{1}{2}$ x 128 x 0.18² = 2.1J

4.Upthrust doesnt depend on the following Physical quantity?

NemiM [27]

Answer:

C: Mass of body

Explanation:

Upthrust is defined as the upward force that a liquid will exert on a body floating atop it.

Now, Formula for upthrust is;

Upthrust = density of liquid × volume of the body × acceleration due to gravity.

From the formula, we can see that upthrust depends on density, volume and acceleration due to gravity.

Thus, looking at the options, the one that doesn't apply is mass of body.

A car traveling at a speed of 13 meters per second accelerates uniformly to a speed of 25 meters per second in 5.0 seconds. 11-

Aleks04 [339]

Answer:

$a=2.4\ m/s^2$

Explanation:

Given that,

Initial speed of a car, u = 13 m/s

Final speed of a car, v = 25 m/s

Time, t = 5 s

We need to find the acceleration of the car during this 5.0 second time interval. Let a is the acceleration. It can be calculated as :

$a=\dfrac{v-u}{t}\\\\a=\dfrac{25-13}{5}\\\\=2.4\ m/s^2$

So, the acceleration of the car is $2.4\ m/s^2$ .
