Answer:

210 m/s

Explanation:

We will use this equation for an elastic collision:

  • m₁v₁ + m₂v₂ = m₁v₁ + m₂v₂  
  • The left side of the equation is before the collision; the right side is after the collision.

In this case, m₁ = mass of golf ball (0.046 kg) and m₂ = mass of the golf club (0.22 kg).

<h3><u>Left side of equation:</u></h3>

v₁ is 0 m/s since the ball is at rest on the tee.

v₂ is 44 m/s, given in the problem.

<h3><u>Right side of equation:</u></h3>

v₁ is what we are trying to find.

v₂ is 0 m/s since the ball will be at rest on the ground.

<h3>⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯</h3>

Plug these values into the elastic collision equation:

  • (0.046 kg)(0 m/s) + (0.22 kg)(44 m/s) = (0.046 kg)(v₁) + (0.22 kg)(0 m/s)

Simplify this equation.

  • (0.22 kg)(44 m/s) = (0.046 kg)(v₁)  

Get rid of the units.

  • (0.22)(44) = 0.046v₁

Multiply the left side of the equation.

  • 9.68 = 0.046v₁

Divide both sides by 0.046.

  • 210.434782609 = v₁
  • 210 m/s = v₁

The speed of the ball when it leaves the tee is about 210 m/s.

A copper rod at 25°C is 2.5 m long. How long would it take a sound to move through the rod from one end to another? how would I
andrew-mc [135]
Length of the copper rod = 2.5 meters
Speed at which sound travels through copper = 3560 meter per second
Let us assume the time taken
by sound to cover the given distance = x seconds
We already know that 
Speed = Distance/ Time
Then
Time = Distance/ Speed
x = 2.5/3560 seconds
   = 0.0007 seconds.
This can ve done by hitting one end of the rod and then receiving the sound at the other end and using the stop clock to measure the time taken.

Which process requires more energy: completely vaporizing 1 kg of saturated liquid water at 1 atm pressure or completely vaporiz
Lilit [14]
The correct answer would be the first option. The process that would need more energy would be vaporizing 1 kg of saturated liquid water at a pressure of 1 atmosphere. This can be seen from the latent heat of vaporization of each system. For the saturated water at 1 atm, the latent heat is equal to 40.7 kJ per mole while, at 8 atm, the latent heat is equal to 36.4 kJ per mole. The latent heat of vaporization is the amount of heat needed in order to vaporize a specific amount of substance without any change in the temperature. As we can observe, more energy is needed by the liquid water at 1 atm.

What travels by vibrating particles? Mechincal Waves or ElecrtoMagnetic Waves.
Naddik [55]

Answer:mechanical waves.

Explanation:

Mechanical waves require the particles of the medium to vibrate in order for energy to be transferred. For example, water waves, earthquake/seismic waves, sound waves, and the waves that travel down a rope or spring are also mechanical waves.
