A cannonball is fired from a cliff that is 50 meters above the ground. The cannonball is fired horizontally with a speed of 120

meters per second.
Calculate the horizontal distance that the cannonball will travel.

The horizontal distance that the cannonball will travel is 383.33m

In order to find the horizontal distance, we will use the formula for calculating the range expressed as:

R = u\sqrt{\frac{2H}{g} } where:

u is the velocity

H is the height

g is the acceleration due to gravity

R = 120\sqrt{\frac{2(50)}{9.8} }\\R = 120\sqrt{\frac{100}{9.8} } \\R=120\times 3.1943\\R=383.33m

Hence the horizontal distance that the cannonball will travel is 383.33m

Does cross transfer occur when fibers are transferred from the victim to the suspect
lesantik [10]
When two people come in contact or when contact occurs with an item from the crime scene, the possibility exists that a fiber transfer will take place. This does not mean that a fiber transfer will always take place. Certain types of fabric do not shed well (donor garments), and some fabrics do not hold fibers well (recipient garments). The construction and fiber composition of the fabric, the duration and force of contact, and the condition of the garment with regard to damage are important considerations.


Hope this helps.

A 8kg cat us running 4 m/s. How much kenetic energy is that
Flauer [41]
     Using the Definition of Kinetic Energy, we have:

E_{c}= \frac{mv^2}{2}  \\ E_{c}= \frac{8*4^2}{2}  \\ \boxed {E_{c}=64J}

Priscilla is driving her car on a busy street and Harvey passes her on his motorcycle. What will happen to the sound from his mo
LiRa [457]

Answer:

the correct answer is A

Explanation:

This is a doppler effect exercise which is the change in frequency due to the relative movement of the sound source and the observer.

          f' = f_o \ \frac{v+v_o}{v-v_s}

where v₀ is the speed of the observer and v_s the speed of the source, the signs correspond when the two are closing in

with this expression let's analyze the different answers

A) True. The observed change is in the frequency, in this case the two are moving away, so the expression that describes the phenomenon is

        f'= f_o \ \frac {v-v_o}{ v+v_s}

In this case, the speed of the source is greater than the speed of the observer, so when the denominator increases faster than the numerator, consequently the frequency must decrease

B) False. The amplitude does not depend on the relative velocity

C) False. The intensity depends on the distance, by or which when increasing the distance the intensity should decrease

D) False. The speed of sound is a constant, if the frequency decreases the wavelength must increase to maintain equality

E) False. The speed of sound depends on the properties of the propagating medium, not on the relative speed of the source and the observer.

Consequently the correct answer is A

Verizon [17]

Answer:

0.625 c

Explanation:

Relative speed of a body may be defined as the speed of one body with respect to some other or the speed of one body in comparison to the speed of second body.

In the context,

The relative speed of body 2 with respect to body 1 can be expressed as :

$u'=\frac{u-v}{1-\frac{uv}{c^2}}$

Speed of rocket 1 with respect to rocket 2 :

$u' = \frac{0.4 c- (-0.3 c)}{1-\frac{(0.4 c)(-0.3 c)}{c^2}}$

$u' = \frac{0.7 c}{1.12}$

u'=0.625 c

Therefore, the speed of rocket 1 according to an observer on rocket 2 is 0.625 c
