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

Helga [31]
Factors such as age, gender, family history, and genetics are <u>nonmodifiable</u><u /> risk factors, while <u>modifiable</u><u /> risk factors are ones that are in your power to change.
You cannot change your age, family history or genetics - you will age no matter what, and you will inherit some traits from your ancestors whether you like it or not. Gender is more flexible nowadays as there are surgeries that can help people change their gender.

The quintessential (most basic/ most important) moment of fertilization of the egg by the sperm cell occurs when
DedPeter [7]

The answer is pronuclei. A pronuclei is the state of the nucleus of either the sperm or the ovum after the sperm has entered the ovum but the two nuclei have not yet fused. When the sperm enters the ovum, the membrane of the sperm pronuclei dissolves hence leaving no barrier for the two genetic materials to combine.
