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
Answer:
D) biophysics.
Explanation:
Hello,
In this case, since biophysics is the study of physical processes and phenomena happening in living things at molecular scale, which includes cells, tissues and organisms. Both experimental and theoretical techniques are used in order to understand biological and biochemical behaviors inside and outside the cells.
Best regards.
