A girl leans against a wall and the wall pushes on the girl.
A baseball hits a glove and the glove pushes on the ball.
A cat rubs up against a tree and the tree pushes against the cat
From conservation of momentum, the ram force can be calculated similarly to rocket thrust:
F = d(mv)/dt = vdm/dt.
<span>In other words, the force needed to decelerate the wind equals the force that would be needed to produce it.
</span><span> v = 120/3.6 = 33.33 m/s
</span><span> dm/dt = v*area*density
</span> dm/dt = (33.33)*((45)*(75))*(1.3)
dm/dt = <span>
146235.375 </span><span>kg/s

</span> This differs by a factor of 2 from Bernoulli's equation, which relates velocity and pressure difference in reference not to a head-on collision of the fluid with a surface but to a fluid moving tangentially to the surface. Also, a typical mass-based drag equation, like Bernoulli's equation, has a coefficient of 1/2; however, it refers to a body moving through a fluid, where the fluid encountered by the body is not stopped relative to the body (i.e., brought up to its speed) like is the case in this problem.
Let the initial velocity of the car be u.
Final velocity of the car (v) = 5.43 m/s
deceleration (a) = - 2.78 m/s^2
Time taken (t) = 2.26 s
Using the first equation of motion:
v = u + at
u = v - at

u = 5.43 + 6.28
u = 11.71 m/s
Let the car's displacement be x.
Using second equation of motion:


x = 26.4646 - 7.0995
x = 19.3651 meters
Hence, the displacement of the car is 19.36 meters
Answer:
There are six major nutrients: Carbohydrates (CHO), Lipids (fats), Proteins, Vitamins, Minerals, Water.
Explanation:
Regardless of whether solar ever truly turns into a noteworthy vitality source here in England is dubious. Up to this point, the UK solar industry had been going from solidarity to quality — in 2016, power delivered from solar power outperformed coal control out of the blue.
There is absolutely enough sunlight in the UK (we get around 60 percent of the sunlight got at the equator) to make putting resources into solar advantageous – as has been exhibited by the development of enormous scale solar tasks in Cornwall and Lincolnshire.
Be that as it may, since the legislature cut its help for the solar industry in 2015, the UK has seen an emotional fall in the rate of take off of solar PV boards. This foolhardy move has additionally activated a large number of occupation misfortunes in the solar industry.
Greenpeace is requiring the English government to desperately audit its help for the solar industry, for the atmosphere and for the effect it has had on the development of clean vitality industry occupations in the UK.
