On a far-away (hypothetical) planet, a student is conducting an experiment to study vertical motion. The student fires a cannon

directly upward, and then records the position of the cannonball every second until it falls back to the ground. Their data is shown in the table below. Based on their data below, answer the following two questions:
1) What is the acceleration due to gravity on this planet? Clearly show how you calculated this.

2) Is there significant air resistance affecting the experiment? Write an evidence-based argument to justify your claim.

- One of the pieces of evidence that you use must be a graph based on the given data. The quantities on the graph are up to you; they can be position and time themselves, or different quantities that you calculate from the given position and time data.

- If you'd like, you can also include outside evidence from your own lab or research. This is not required; only include it if it makes your argument stronger.

Answer both questions on one document. The document can be digital, hand-written, or a mix of both (copy and paste images of your handwritten work into a doc).

After polishing his 2-kg wrestling trophy, Mike sets it down on the ground and walks away to find more polish. Meanwhile, Julie
klio [65]

1) The initial momentum of the trophy is zero

2) The initial momentum of the bowling ball is 160 kg m/s

3) The total momentum before the collision is 160 kg m/s

4) The total momentum of the system after the collision is 160 kg m/s

5) The final velocity of the trophy is 32 m/s

Explanation:

1)

The momentum of an object is given by

p=mv

where

m is the mass of the object

v is its velocity

In this problem, the data for the trophy before the collision are:

m = 2 kg is the mass

v = 0 is its initial velocity

Therefore, the initial momentum of the trophy is

p_1=(2)(0)=0

2)

Using the same equation used in part 1), the initial momentum of the bowling ball is

p=mv

where

m is the mass of the bowling ball

v is its initial velocity

The data of the problem are

m = 8 kg is the mass

v = 20 m/s is the velocity

Substituting,

p_2=(8)(20)=160 kg m/s

3)

The total momentum of the system before the collision is given by the sum between the initial momentum of the trophy and the initial momentum of the bowling ball:

p_i = p_1 + p_2

where

p_1 is the initial momentum of the trophy

p_2 is the initial momentum of the ball

Here we have

p_1 = 0

p_2 = 160 kg m/s

Therefore, the total momentum is

p_i = 0 + 160 = 160 kg m/s

4)

According to the law of conservation of momentum, for an isolated system (=no external unbalanced forces acting on the system), the total momentum of the system is conserved before and after the collision:

p_i = p_f

where

p_i is the total momentum before the collision

p_f is the total momentum after the collision

If we consider the system in the problem to be isolated (i.e. no frictional forces acting on the ball or the trophy), we can therefore say that the total momentum after the collision must be equal to the total momentum before the collision: therefore,

p_f = 160 kg m/s

5)

We can write the total momentum after the collision as

p_f = m_1 v_1 + m_2 v_2

where:

m_1 = 2 kg is the mass of the trophy

v_1 is the final velocity of the trophy

m_2 = 8 kg is the mass of the bowling ball

v_2 = 12 m/s is the final velocity of the ball

Since we also know the value of the final total momentum,

p_f = 160 kg m/s

we can solve the equation to find the velocity of the trophy:

v_1 = \frac{p_f - m_2 v_2 }{m_1}=\frac{160-(8)(12)}{2}=32 m/s

Find the wavelength of a 26 Hz sound wave traveling through air at 20ºC. Hint: speed of sound at 20ºC = 343 m/s
Usimov [2.4K]
The correct answer for the question that is being presented above is this one: "B. 13m." 

The formula of wave velocity is this:
wave velocity = f * <span>λ
</span>λ = v / f
<span>λ</span> = 343m/s / 26Hz
λ = 13.20m .. ans (b) 

Here are the following choices:
A. 5m 
B. 13m 
C. 28m 
D. 58m
