Answer:
The speed is 20.8 m/s
Step-by-step explanation:
If a projectile ascends vertically, and after 3 seconds it reaches its maximum height, calculate the velocity that it carries to the middle of its downward trajectory
Let the maximum height is h and initial velocity is u.
From first equation of motion
v = u + at
0 = u - g x 3
u = 3 g.....(1)
Use third equation of motion
Let the speed at half the height is v'.
Answer: 1696.46
Step-by-step explanation:
6 x 6 x 3.14 = 113.1
24 x 24 x 3.14 = 1809.56
113.1 - 1809.56
thus we have 1696.46
sorry had to edit some things instead of one 6 its 6 x 6 and same with 24
The answer is 6x-7y=21
In order to find this answer you need to convert the answer choices into y intercept form by isolating the y variable to one side of the equation.
6x-7y=21
-7y=-6x+21
y=6/7x-3
As you can see when you change the form of this equation, the y intercept is -3.
Answer:
11
Step-by-step explanation:
LN = LM + MN
=> 22 = 3z + 1 + 3z + 1
20 = 6z
z = 10/3
LM = (10/3)*3+1 = 11
