A driver of a car traveling at 14.6 m/s applies the brakes, causing a uniform deceleration of 1.2 m/s2. How long does it take th

vfiekz [6]

Recall that

$v_f=v_0+at$

It takes the car about 3.2 s to reduce its speed from 14.6 to 10.8 m/s, since

$10.8\,\dfrac{\mathrm m}{\mathrm s}=14.6\,\dfrac{\mathrm m}{\mathrm s}+\left(-1.2\,\dfrac{\mathrm m}{\mathrm s^2}\right)t\implies t=3.2\,\mathrm s$

Next, recall that

$\Delta x=x_f-x_0=\dfrac{v_f+v_0}2t$

Then the car undergoes a displacement of about 41 m, since

$\Delta x=\dfrac{10.8\,\frac{\mathrm m}{\mathrm s}+14.6\,\frac{\mathrm m}{\mathrm s}}2(3.2\,\mathrm s)\implies\Delta x=41\,\mathrm m$

An infinite sheet of charge is located in the y-z plane at x = 0 and has uniform charge denisity σ1 = 0.37 μC/m2. Another infini

Answer:

The x-component of the electric field at point P -- 31,638.41

Explanation:

Given data:

charge density $\sigma_1 =0.37 \muC/m^2$

Another charge density $\sigma_2 = -0.19 \mu C/m^2$

Electric field due to infinite sheet of charge is given as E

$E = \frac{\sigma}{2\epsilon}$

$E_{NET} = E_1 + E_2$

$= \frac{\sigma_1}{2\epsilon} + \frac{\sigma_2}{2\epsilon}$

$= \frac{0.37\times 10^{-6}}{2\times 8.85\times 10^{-12}} + \frac{0.19\times 10^{-6}}{2\times 8.85\times 10^{-12}}$

= 31,638.41

What happen to the weight of a body when it is falling freely under the action of gravity?

mr Goodwill [35]

Answer:

Explanation:

where W-weight, m-mass of the object and g-acceleration produced due to the earth's gravity. ... This happens because the normal reaction force exerted on the object in the lift is equal to zero, and normal force equals to mg, which in turn equals the weight of the object.
