A hockey player uses a hockey stick to hit a puck such that the stick provides an applied force on the puck. The puck travels fo

r distance of 0.85m while experiencing the force from the stick. The puck leaves the stick with a speed of 8.0m/s and travels at constant speed in a straight line along the horizontal ice for a distance of 12m. The frictional force between the puck and the ice surface is negligible. How does the magnitude of the force exerted by the stick on the puck Fpuck,stick compare to the magnitude of the force exerted by the puck on the stick Fstick,puck at the time interval in which the stick is in contact with the puck?

Answer:

Fpuck,stick= Fstick,puck

Step-by-step explanation:

Force exerted by the stick on the puck is equal to the force exerted by the puck on the stick.

From Newton's third law of motion, we know that action and reaction are equal and opposite.

a force is that which tends to change a body;'s state of rest or uniform motion in a straight line. the impact by the stick on the puck produces  an acceleration . on the puck, the impact by the puck on the stick produces an acceleration on the stick although, little.

F1=F2

Notice also that the total momentum before collision is equal to the momentum after collision. The collision is elastic.

Sarah is the president of the drama club and wants to publish a newspaper. Expenses are $.90 for printing and mailing each copy,
larisa86 [58]
Let: x = number of copies sold

We can formulate the following equation to solve for x:

1.50x - 0.9x - 600 = 0

x = 1000

Therefore, the club must sell 1000 copies to break even. Among the choices, the correct answer is A.

You and your best friend are meeting at
chubhunter [2.5K]

Answer:

  10.6 miles

Step-by-step explanation:

The corner where Starbucks is located could be considered to be the right angle in a right triangle having legs of 8 miles (distance to you) and 7 miles (distance to your friend). The straight-line distance (d) from you to your friend is the hypotenuse of that triangle. Its length can be found from the Pythagorean theorem.

  d² = 8² +7²

  d² = 64 +49 = 113

  d = √113 ≈ 10.6

You and your friend are about 10.6 miles from each other.

I really need help I don’t understand how to do this
krek1111 [17]

Answer:

Step-by-step explanation:

Remark

The way this is worded, it sounds like it is a horizontal distance. However by the marking it looks like they want the hypotenuse. Life can be very confusing sometimes.

The angle of the triangle that you need to know is the one on the right. The line of sight line is parallel to the base of the triangle. So the angle on the right is 8 degrees by the Z theorem.

Solution

Sin(8) = 1817 / x           Multiply both sides by x

x*sin(8) = 1817             Divide by sin(8)

x = 1817/sin(8)

sin(8) = 0.1392

x = 1817/0.1392

x = 13055.7

Note

Watch how you do this. I would put it into your calculator as

1817

÷

sin(8)

=

If you use the rounded answer I gave for sin(8), you might get it wrong. This is a big distance and you should just use the exact number you get for sin(8).

Answer and explanation please!!
Mandarinka [93]

Answer:

Area of the rhombus, A = 22.5 sq. ft.

Step-by-step explanation:

The area of a rhombus = a. b

where, a = side of the rhombus

and      b = height of the rhombus.

Here, the side, a = 5 ft

Height, b = 4.5 ft.

Therefore, area, A = 5 X 4.5 sq. ft

⇒ A = 22.5 sq. ft which is the required answer.
