Initial velocity v = 86.6 m / s
angle ,theta = 63.7 degrees
(A). the horizontal component of the shell's initial velocity = v cos 63.7 = 38.36 m / s
vertical component of shells' initial velocity = v sin 63.7 = 77.63 m / s
(B). time taken to reach maximu height t = v sin (theta ) / g
= 7.922 s
(C). Maximum height H = ( v sin(theta) )^ 2/ 2g
= 307.5 m
(D). Required distance = v^ 2 *sin2(theta) / g
= 607.9 m
(E). Horizontal component of accleraton = 0
vertical component of accleration = g = 9.8 m / s^ 2
(F). horizontal component of velocity at required point = v cos (theta ) = 38.36 m / s
vertical compoent of velocity at required point = 0
The answer to this is At least 16.6 meters in front of the reflecting surface.
The speed of sound without any interference is only about 340 m/s through the vibration of the media in which it passes through.
Hope this helped :)
Have a great day <span />
A mechanical wave travels through a median, an electro magnetic wave fan travel without a median because it is caused by the oscicillation of an electric and magnetic wave
Answer:
or
Explanation:
Answer is attached. I do not know if you needed to use 9.81 or 10 for the acceleration due to gravity, so both solutions are attached.
