Momentum is never created or destroyed. It is conserved.

The cue stick gave the cue ball all the momentum there is on the table. There's nothing on the table that can pour in any more momentum.

After the strike, with 15 or 16 balls rolling every which way around the table, the total momentum of all of them combined will be the same as the cue ball's momentum right now, before the strike.

Which of the following is the correct equation we get

UkoKoshka [18]

Answer:

$\frac{a}{b}=c$ which agrees with the third answer in your list of answer options

Explanation:

Start with:

$a=b\,*\,c$

divide both sides by b to isolate c on the right:

$\frac{a}{b} =\frac{b\,*\,c}{b} \\\frac{a}{b} =c$

2) A sprig with a length of 15 cm and stores 110 J of potential energy when stretched to a new

Alik [6]

Answer:

94.28 cm

Explanation:

The formula for elastic potential energy is given as;

PEel = 1/2 *k*x² where x is the displacement, k is the spring constant

Given

PEel = 110 J, k= 350 N/m then find x

PEel = 1/2 *k*x²

110 = 1/2 * 350 * x²

110 = 175 x²

110/175 = x²

0.6286=x²

√0.6286 =x

0.7928 m = x

79.28 cm = x

New length of spring = 15 cm + 79.28 cm = 94.28 cm

The inclined plane in the figure above has two sections of equal length and different roughness. The dashed line shows where sec

The static friction exerted on the block by the incline is $\mu _ s _1 Mgcos \ \theta$ .

The given parameters;

mass of the block, = M
coefficient of static friction in section 1, = $\mu_s_1$
angle of inclination of the plane, = θ

The normal force on the block is calculated as follows;

Fₙ = Mgcosθ

The static friction exerted on the block by the incline is calculated as follows;

$F_s = \mu_s F_n\\\\F_s = \mu _s_1(Mg cos\ \theta)\\\\F_s = \mu _s_1 Mgcos\ \theta$

Thus, the static friction exerted on the block by the incline is $\mu _ s _1 Mgcos \ \theta$
