A cylinder is given a push and then rolls up an inclined plane. If the origin is the starting point, sketch the position, veloci

ty, and acceleration of the cylinder vs. time as it goes up and then down the plane.

It will take a shorter amount of time for the cylinder to go down the plane down off the plane Because more pressure is applied one going up then going down there’s no pressure at all it’s the gravity is helping

Two students play tug of war. Jack pulls East with a force of 82 Newtons while Tony pulls west with a force of 96 Newtons. Which
lorasvet [3.4K]

The net force on the center of the rope is C. 14 N West

Explanation:

We have two forces acting on the rope:

- The force applied by Jack, 82 N, towards East

- The force applied by Tony, 96 N, towards West

Taking East as positive direction, we can rewrite the two forces as

F_1 = +82 N\\F_2 = -96 N

where the second force is negative since its direction is west.

The two forces act along the same line, so we can calculate their resultant by simply calculating their algebraic sum. Therefore:

F=F_1+F_2=+82+(-96)=-14 N

And the negative sign tells us that the direction is West.

Chegg ) Alice owns 20 grams of a radioactive isotope that has a half-life of ln(4) years. (a) Find an equation for the mass m(t)
stepladder [879]

Answer:

m(t)=20e^{-0.5t}

Explanation:

Given:

Initial mass of isotope (m₀) = 20 g

Half life of the isotope (t_{1/2}) = (ln 4) years

The general form for the radioactive decay of a radioactive isotope is given as:

m(t)=m_0e^{-kt}

Where,

m(t)\to mass\ after\ 't'\ years\\t\to years\ passed\\k\to rate\ of\ decay\ per\ year

So, the equation is: m(t)=20e^{-kt}

At half-life, the mass is reduced to half of the initial value.

So, at t=t_{1/2},m(t)=\frac{m_0}{2}. Plug in these values and solve for 'k'. This gives,

\frac{m_0}{2}=m_0e^{-k\times\ln 4}\\\\0.5=e^{-k\times\ln 4}\\\\Taking\ natural\ log\ on\ both\ sides,we\ get:\\\\\ln(0.5)=-k\times \ln 4\\\\k=\frac{\ln 0.5}{-\ln 4}=0.5

Hence, the equation for the mass remaining is given as:

m(t)=20e^{-0.5t}
