Answer:
t = 6 s
Explanation:
Given that,
A chair is thrown upward from a balcony that's 96 ft in the air, d = 96 ft
The initial velocity of chair, u = 16 ft/s
We need to find how many seconds does the chair take to reach its highest height. Let the time is t.
Hence, the chair take 6 seconds to reach its maximum height.
Answer:
Explanation:
Given
Weight of helicopter 
inclination of blades with vertical 
Suppose 
is the lifting Force
Now using F-B-D
as helicopter is moving with constant velocity
balancing forces in Vertical Force
Now sin component of lift is air resistance
where R=air resistance
From a to b speed is 600+40 = 640
from b to a speed is 600-40 = 560
let t be the number of hours of flight. This would mean it would have traveled a distance of 640 miles and the distance yet to travel is 2400-640t
Time left will be (2400-640t)/640. But if they were to return to a it would fly 640t miles at 560mph which will take (640t/560) hrs
(2400-640t) / 640 = 640t / 560
560(2400 - 640t) = 640t x 640
t = 1.75hrs
Answer:
3.4 or 3 11/23
Explanation:
just dive so you can see it as if it were Evelyn distributed
