Answer:

  • time: 1.122 seconds
  • range: 10.693 m
  • maximum height: 1.543 m

Explanation:

<u>Given</u>:

  runner is launched at 30° angle to horizontal at 11 m/s

  acceleration due to gravity is g = -9.8 m/s²

<u>Find</u>:

  runner's hang time

  runner's distance to the landing point

  runner's maximum height

<u>Solution</u>:

The (horizontal, vertical) speed components will be ...

  (11 m/s)(cos(30°), sin(30°)) = (5.5√3 m/s, 5.5 m/s)

The time of flight can be found from the height formula:

  h(t) = 1/2gt² +vt . . . . . . where v is the vertical speed at launch

The time we're concerned with is the time when h(t)=0 and t>0.

  0 = -4.9t^2 +5.5√3t = t(-4.9t +5.5√3)

The second factor is zero when ...

  t = (5.5√3)/4.9 ≈ 1.122 . . . seconds hang time

__

The distance to the landing point will be the product of horizontal speed and hang time:

  d = (5.5 m/s)(5.5√3/4.9 s) ≈ 10.693 m . . . . distance to landing

__

The maximum height can be found from the formula (based on conversion of kinetic energy to potential energy) ...

  h = v²/|2g| = (5.5 m/s)²/(2(9.8 m/s²)) ≈ 1.543 m . . . . maximum height

WILL MARK BRAINLIST IF MAKES SENSE
bija089 [108]

Answer:

Latitude provides the location of a place north or south of the equator and is expressed by angular measurements ranging from 0° at the equator to 90° at the poles. Different latitudes on Earth receive different amounts of sunlight, and are a key factor in determining a region’s climate. For example, the higher the latitude of a given place (the farther away it is from the equator), the sharper the angle of the sun’s rays that reach it, meaning that the rays of the sun are spread across a broader area. Therefore, higher latitudes receive less heat than lower latitude areas nearer the equator.

-The mutation could make it easier for an organism to obtain food.
-yes, a correct anwer!

-The mutation could make an organism need more food.
-no, this would make it harder for the organism to survive

-The mutation could improve the organism's sight.
-yes! better sight means more information, which is beneficial

- The mutation could let the organism run faster.
-running faster means advantage over pray and predator - also a correct answer

so all are correct except on the second one.
