An alert driver can apply the brakes fully in about 0.5 seconds. How far would the car travel if it

Physics
1 answer:
dybincka [34]4 years ago
8 0

Answer:

The car would travel after applying brakes is, d = 14.53 m

Explanation:

Given that,

The time taken to apply brakes fully is, t = 0.5 s

The velocity of the car, v = 29.06 m/s

The distance traveled by the car in 0.5 s, d = ?

The relation between the velocity, displacement, and time is given by the formula                

                                d = v x t    m

Substituting the values in the above equation,

                                  d = 29.06 m/s x 0.5 s

                                     = 14.53 m

Therefore, the car would travel after applying brakes is, d = 14.53 m

In gas chromatography, what are the advantages of (a) temperature programming? (check all that apply.)
TiliK225 [7]
The following statements apply:
1. Resolution of low boiling solutes is maintained.
2. Retention times of high boiling solutes are decreased.
Temperature programming refers to the process of increasing the temperature of gas chromatography column as a function of time. Temperature programming is usually applied to samples which contain a mixture of components whose boiling points are within narrow ranges

What is the speed of a wave frequency of 300hz and a wavelength of 25M
tia_tia [17]

Answer:

7500 m/s

Explanation:

We can use the equation velocity of a wave equals wavelength times  frequency.  Therefore, v = wavelength*f = (25 m)(300 Hz) =  m/s7,500

A car initially traveling at 27.7 m/s undergoes a constant negative acceleration of magnitude 2.00 m/s2 after its brakes are app
lys-0071 [83]

The car's velocity at time <em>t</em> is given by

v=27.7\dfrac{\rm m}{\rm s}+\left(-2.00\dfrac{\rm m}{\mathrm s^2}\right)t

It comes to a stop when <em>v</em> = 0, which happens when

0=27.7\dfrac{\rm m}{\rm s}+\left(-2.00\dfrac{\rm m}{\mathrm s^2}\right)t\implies t=13.85\,\mathrm s

or after about 13.9 s.

In this time, the car travels a distance <em>x</em> given by

x=\left(27.7\dfrac{\rm m}{\mathrm s}\right)(13.85\,\mathrm s)+\dfrac12\left(-2.00\dfrac{\rm m}{\mathrm s^2}\right)(13.85\,\mathrm s)^2=191.823\,\mathrm m

or about 192 m.

In one complete revolution, each tire covers a distance equal to its circumference,

2\pi(0.340\,\mathrm m)\approx2.13628\,\mathrm m

or about 2.14 m.

This means each tire will complete approximately 192/2.14 ≈ 90 revolutions.

Explanation:

It is given that

The kinetic energy of  Mr. Thomson’s prius, K = 641300 J

He is moving with a velocity, v = 22 m/s

It is required to find the mass of Mr. Thomson’s prius.

Due to his motion, a kinetic energy will possess by him. The mathematical form of kinetic energy is given by :

K=\dfrac{1}{2}mv^2

Solving for m

m=\dfrac{2K}{v^2}

Plugging all the values, we get :

m=\dfrac{2K}{v^2}\\\\m=\dfrac{2\times 641300}{(22)^2}\\\\m=2650\ kg

So, the mass of Mr. Thomson’s prius is 2650 kg.
