28.65m x 15.24m
Explanation:
The size of a basketball court in the NBA is usually 28.65m x 15.24m giving a total court area of 436.62m².
The NBA is the acronym for National Basketball Association. It comprises of several teams from across United states and Canada in basketball league.
- The game is played by hand with a target basket.
- For each successive throw into the basket, 1 or 2 or 3 points can be awarded.

- From the dimension we can accurately say that a basketball court is rectangular in shape.
- James Naismith is credited with the invention of the game of basketball

Answer:
The normal force is 85,42 N
Explanation:
There is no friction force, therefore there is no relationship between the normal force and the friction.
We can find the normal force using a free body diagram and check the forces that are acting on the sled. The total forces are equal to 0 because there is no movement in the y-axis. The movement exists only on the x-axis.
Yo don’t click the link that guy says dude I think it’s like tracking or something
The only vertical forces are weight and normal force, and they balance since the surface is horizontal. The horizontal forces are the applied force (uppercase F) in the direction the block slides and the frictional force (lowercase f) in the opposite direction.
Apply Newton's 2nd Law in the horizontal direction:
ΣF = ma
F - f = ma
where f = µmg
F - µmg = ma
F = m(a +µg)
F = (20 kg)(1.4 m/s² + 0.28(9.8 m/s²)
F = 83 N
Answer:
8 minutes and 20 seconds
Explanation:
Average Distance between Earth and Sun: 150 million km = 
km
Velocity of light: 
Time = Distance/Speed
or Time = 
/ 
= 5 * 100
= 500 seconds
⇒ Time = 8 minutes and 20 seconds
