Explain how the net impact forces can be reduced for basketball players through the

Physics
1 answer:
Dima020 [189]3 years ago
4 0

Answer:

* If we increase the distance traveled before stopping, the forces decrease significantly,

* If we decrease the height of the fall by grabbing the net to slow down.

* Creating a process of absorption of force in the shoes, through the deformation of the elastic soles.

Explanation:

When basketball players jump to place the ball in the net they see from a good height, when they hit the ground, strong tensions are produced in the bones and bonds.

Applying science to this case of fall, we can suggest several processes to decrease the forces on impact.

* If we increase the distance traveled before stopping, the forces decrease significantly,

* If we decrease the height of the fall by grabbing the net to slow down.

* Creating a process of absorption of force in the shoes, through the deformation of the elastic soles.

By designing shoes that have some degree of force absorption, it is possible to significantly reduce the stress on the player.

Ignoring air​ resistance, an object in free fall will fall d feet in t​ seconds, where d and t are related by the algebraic mode
Lostsunrise [7]

Explanation:

Given that,

An object in free fall will fall d feet in t​ seconds, where d and t are related by the algebraic model as :

d=16t^2..........(1)

(a) We need to find the time taken by the object to fall 1148 ft. Put this in equation (1) as :

16t^2=1148

t=\sqrt{71.75}

t = 8.47 seconds

(b) If the object is in free fall for 18.5 sec after it is​ dropped, then the height of the object is given by :

d=16(18.5)^2

d = 5476 ft

Hence, this is the required solution.

The dark bands on the wall are from ______________ interference. and i will give brainlyest
Fittoniya [83]
Light can be seen as an electromagnetic wave.
What happens when two waves, with the same frequency, superpose is called interference.

If at a certain point two waves arrive both with a crest, we have constructive interference and the amplitudes sum up, reaching the maximum value, resulting in bright spots.

If at a certain point one of the waves arrives with a crest and the other wave arrives with a trough, we have destructive interference, and the two amplitudes cancel out, resulting in dark spots.

Therefore, t<span>he dark bands on the wall are from destructive interference.</span>

Consider the electronic elements that are cooled by forced convection in Problem 6.31. The cooling system is designed and tested
Stella [2.4K]

Answer:

surface temperature of the chip located 120 mm Ts=42.5°C

surface temperature of the chip in Mexico Ts=46.9°C

Explanation:

from the energy balance equation we have to:

q=E=30W

from Newton´s law:

Ts=Tα+(q/(h*A)), where A=l^2

N=h/k=0.04*(Vl/V)^0.85*Pr^1/3

data given:

l=0.12 m

v=10 m/s

k=0.0269 W/(m*K)

Pr=0.703

Replacing:

h=0.04*(0.0269/0.12)*(10*0.12)/((16*69x10^-6))^0.85*(0.703^1/3) = 107 W/m^2*K

The surface temperature at sea level is equal to:

Ts=25+(30x10^-3/107*0.004^2)=42.5°C

h=0.04*(0.0269/0.12)*((10*0.12)/(21*81x10^-6))^0.85*(0.705^1/3)=85.32 W/(m*K)

the surface temperature at Mexico City is equal to:

Ts=25+(30x10^-3/85.32*0.004^2)=46.9°C
