- 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
Answer:
Explanation: Sponges are animals with dense skeletons that are highly adapted to their environments.
The correct answer is adaptation.
Pollination refers to the procedure of transferring the pollen grain from the anther of a stamen to the stigma of a carpel. Some plants are amended for pollination by the wind, and some for pollination by insects.
The plants, which are adapted for pollination via insects exhibit colorful petals and nectar to attract the insects, and sticky pollen, which adheres to the insects when they visit the flowers.
Answer:
During El Nino and LA Nina, opposing weather conditions are observed
Explanation:
Both El Niño and La Niña are weather patterns that occurs in the Pacific Ocean. It causes changes in global temperature and rainfall levels.
