Answer:
c = 5 m
Explanation:
this exercise you want to divide the rectangular room into two triangular rooms
the area of triangles is
A = ½ base height
A = ½ 4 3
A = 6 m²
the length of the curtain can be found using the Pythagorean theorem
c² = b² + a²
c = √ (4² + 3²)
c = 5 m
this is the length of the curtain
Answer:
CALCIUM IDENINE ADEININE AND PHOSPHATE
Explanation:
We have that the instantaneous velocity of the
shuttlecock when it hits the ground is
![V_{int}=\sqrt{U^2+19.6H}](https://tex.z-dn.net/?f=V_%7Bint%7D%3D%5Csqrt%7BU%5E2%2B19.6H%7D)
From the question we are told
Assuming the acceleration is still -9.81 m/s2, what is the instantaneous velocity of the
shuttlecock when it hits the ground? Show your work below.
Generally the equation for acceleration is mathematically given as
![a=v \frac{dv}{dx}\\\\\Therefore\\\\\2ah=v^2-u^2](https://tex.z-dn.net/?f=a%3Dv%20%5Cfrac%7Bdv%7D%7Bdx%7D%5C%5C%5C%5C%5CTherefore%5C%5C%5C%5C%5C2ah%3Dv%5E2-u%5E2)
Where
acceleration is still -9.81 m/s2,
Hence,
![V^2-U^2=2(-9.81)*-H](https://tex.z-dn.net/?f=V%5E2-U%5E2%3D2%28-9.81%29%2A-H)
Therefore
![V_{int}=\sqrt{U^2+19.6H}](https://tex.z-dn.net/?f=V_%7Bint%7D%3D%5Csqrt%7BU%5E2%2B19.6H%7D)
