How significant is air resistance for projectile motion?

Physics
1 answer:
miv72 [106K]3 years ago

Answer:

Air resistance have some significant role in projectile motion if the motion lasts for some time.

Explanation:

  • Air resistance or air drag seems to be important in daily actvities and games like baseball.
  • The trajectory of the projectile with or without air resistance or air drag is totally different.
  • When we neglect air drag, the only acting force is gravity against the motion so the maximum height and range are suppose Hmax and R.
  • Now, when we consider air drag, it is important to notice that there are two forces against the motion of the ball and along the direction of gravity. It seems that both maximum height and range are lesser Hmax'< Hmax and R'<R.

Lisa [10]

Out of the following given choices;

A) It is always difficult to get a project like this approved. This study will help them convince the local community to support the project.

B) If they do not perform the study, and there is a problem during the dredging project, the media could make them look bad.

C)The study will weigh the benefits against the negative impacts so an informed decision can be made.

D)The study will demonstrate the local government's concern for the community's safety.


The answer is; C

Dredging can have a negative impact on the marine environment. Destruction of this ecosystem could have reverberating effects that affect the communities that rely on this ecosystem for livelihoods, such as fishermen. An environmental and feasibility study will help weigh the benefits and demerits of the project and allow for an informed decision to be made.

PLEASE HELP ME WITH THIS ONE QUESTION
BlackZzzverrR [31]

Answer:

Vf = 0.0108 m³

Explanation:

Assuming there is no change in internal energy, we can calculate the changed volume by the following formula:

Energy\ Supplied = Work = W = P \Delta V \\W = P(V_{f}-V_{i})\\

where,

W = Work = Energy Supplied = 1000 J

P = Pressure = 101325 Pa

Vf = Final Volume = ?

Vi = Initial Volume = 0.001 m³

Therefore,

1000\ J = (101325\ Pa)(V_{f}-0.001\ m^3)\\\\V_{f}-0.001\ m^3 = \frac{1000\ J}{101325\ Pa}\\\\V_{f} = 0.001\ m^3 + 0.0099\ m^3

<u>Vf = 0.0108 m³</u>
