How can athletes promote social<br> justice?
CaHeK987 [17]

ORLANDO, Fla. —

The NBA playoffs will pick up again this weekend after players made a powerful statement on Wednesday.

Athletes have a voice when it comes to change and demands for social justice. Their impact is extending off the court and into the world.

"We stand with them, we support them and we're there for them," Michael-Carter Williams said.

The Orlando Magic's Michael Carter-Williams spoke Thursday about the Milwaukee Bucks' decision not to play Wednesday and instead, making a demand for the end to social injustice.

"We have a big platform that we can use to really make change in this country and we can go home to our communities and make change there," Carter-Williams said.

The Bucks' decision led to all NBA games being postponed Wednesday, some baseball games weren't played, as well as soccer, and the WNBA.

"This was a historic moment last night, we never had anything like that happen before," Dr. Richard Lapchick said.

Lapchick is a UCF professor who is also the president of the Institute for Sport and Social Justice.

He says the impact from Wednesday's boycott can't be overstated.

"The unity that occurred between the players and teams and leagues, was particularly impressive," Lapchick said. "The importance of what the players are doing, and what the country is doing in response, is looking at more than police brutality, it's looking at systemic racism."

"People are just tired of what's going on, there's no justice at all," Sandy Lallavee said.

Lallavee is one of the many residents we spoke to who supports the athletes' desire for a committed dialogue and effective change.

"I think it's the right thing to do right now, I support their decision and I think it's terrible what's happening in the world, in America," Gerrod Trytten said.

"It's a younger generation doing things and trying to make change, I respect them and I think they're doing the right thing," Nick Trapp said.

"They're showing their humanity, they're showing what they really care about in society," Lapchick said.

A spaceship moves radially away from Earth with acceleration 29.4 m/s 2 (about 3g). How much time does it take for sodium street
Gemiola [76]

Answer:

doppler shift's formula for source and receiver moving away from each other:

<em>λ'=λ°√(1+β/1-β)</em>

Explanation:

acceleration of spaceship=α=29.4m/s²

wavelength of sodium lamp=λ°=589nm

as the spaceship is moving away from earth so wavelength of earth should increase w.r.t increasing speed until it vanishes at λ'=700nm

using doppler shift's formula:

<em>λ'=λ°√(1+β/1-β)</em>

putting the values:

700nm=589nm√(1+β/1-β)

after simplifying:

<em>β=0.17</em>

by this we can say that speed at that time is: v=0.17c

to calculate velocity at an acceleration of a=29.4m/s²

we suppose that spaceship started from rest so,

<em>v=v₀+at</em>

where v₀=0

so<em> v=at</em>

as we want to calculate t so:-

<em>t=v/a</em>                                                v=0.17c      ,c=3x10⁸           ,a=29.4m/s²

putting values:

=0.17(3x10⁸m/s)/29.4m/s²

<em>t=1.73x10⁶</em>
