You push a heavy crate out of a carpeted room and down a hallway with a waxed linoleum floor. While pushing the crate 2.5 m out
Alinara [238K]

Answer:

W = 1562.5 J

Explanation:

Path 1:

W₁ = F₁*d₁ = 385 N * 2.5 m = 962.5 J

Path 2:

W₂ = F₂*d₂ = 130 N * 10 m = 1300 J

Path 3:

W₃ = F₃*d₃ = (-350 N) * 2 m = - 700 J  (opposite to the motion)

We get

W = W₁ + W₂ + W₃ = 962.5 J + 1300 J + (- 700 J) = 1562.5 J

A 591 μF capacitor is discharged through a resistor, whereby its potential difference decreases from its initial value of 88.5 V
Stels [109]

Answer:

2.6 kilo Ohm

Explanation:

Capacitance, C = 591 μF = 591 x 10^-6 F

Vo = 88.5 V

V = 11.9 V

t = 3.09 s

Let the resistance is R.

V = V_{0}e^{\frac{-t}{RC}}

\frac{11.9}{88.5} = e^{\frac{-t}{RC}}

0.135 = e^{\frac{-t}{RC}}

Take natural log on oth the sides

ln 0.135 = - 3.09 / RC

RC = 1.545

R = 1.545 / ( 591 x 10^-6)

R = 2614.2 ohm

R = 2.6 kilo Ohm

Thus the resistance is  2.6 kilo Ohm.

svetoff [14.1K]

Answer:

v = (v_0^{\frac{3}{2}}-\frac{3cx}{2m})^\frac{2}{3}

x = \frac{2m}{c}*v_0^{\frac{3}{2}}

Explanation:

Given

f(v) =- cv^\frac{1}{2}

To start with, we begin with

F = ma

Substitute the expression for F

-cv^\frac{1}{2} = ma

-ma = cv^\frac{1}{2}

Acceleration (a) is:

a = \frac{dv}{dt}

So, the expression becomes:

m\frac{dv}{dt} = -cv^\frac{1}{2}

-----------------------------------------------------------------------------------------

Velocity (v) is:

v = \frac{dx}{dt} --- distance/time

v * \frac{dv}{dx}= \frac{dx}{dt}* \frac{dv}{dx}

v * \frac{dv}{dx}= \frac{dv}{dt}

\frac{dv}{dt} = v * \frac{dv}{dx}

--------------------------------------------------------------------------------------------

So, we have:

m\frac{dv}{dt} = -cv^\frac{1}{2}

mv * \frac{dv}{dx} = -cv^\frac{1}{2}

Divide both sides by v^\frac{1}{2}

mv^{1-\frac{1}{2}} * \frac{dv}{dx} = -c

mv^{\frac{1}{2}} * \frac{dv}{dx} = -c

Divide both sides by m

v^{\frac{1}{2}} * \frac{dv}{dx} = -\frac{c}{m}

v^{\frac{1}{2}} * dv = -\frac{c}{m} * dx

Integrate:

\int\limits^v_{v_0} {v^{\frac{1}{2}}} \, dv  = -\frac{c}{m}\int\limits^x_0 {}} \, dx

\frac{2}{3}v^{\frac{3}{2}}|\limits^v_{v_0}  = -\frac{c}{m}x|\limits^x_0

\frac{2}{3}(v^{\frac{3}{2}} - v_0^{\frac{3}{2}} ) = -\frac{cx}{m}

v^{\frac{3}{2}} - v_0^{\frac{3}{2}} = -\frac{3cx}{2m}

v^{\frac{3}{2}} = v_0^{\frac{3}{2}}-\frac{3cx}{2m}

v = (v_0^{\frac{3}{2}}-\frac{3cx}{2m})^\frac{2}{3}

Next, is to get the maximum velocity by distance x.

To do this, we find the derivation by x

\frac{dv}{dx} = 0

\frac{2}{3}(v_0^{\frac{3}{2}}-\frac{3cx}{2m})^{\frac{2}{3} - 1} * -\frac{3c}{2m} = 0

\frac{2}{3}(v_0^{\frac{3}{2}}-\frac{3cx}{2m})^{\frac{2-3}{3}} * -\frac{3c}{2m} = 0

\frac{2}{3}(v_0^{\frac{3}{2}}-\frac{3cx}{2m})^{\frac{-1}{3}} * -\frac{3c}{2m} = 0

(v_0^{\frac{3}{2}}-\frac{3cx}{2m})^{\frac{-1}{3}} * -\frac{c}{m} = 0

Divide both sides by -\frac{c}{m}

(v_0^{\frac{3}{2}}-\frac{3cx}{2m})^{\frac{-1}{3}} = 0

Take cube roots of both sides

(v_0^{\frac{3}{2}}-\frac{3cx}{2m})^{-1} = 0

v_0^{\frac{3}{2}}-\frac{3cx}{2m} = 0

\frac{3cx}{2m} = v_0^{\frac{3}{2}}

x = \frac{2m}{c}*v_0^{\frac{3}{2}}
