Your answer would be A):Organize a laboratory in Germany.
Answer:
H = 1/2 g t^2 where t is time to fall a height H
H = 1/8 g T^2 where T is total time in air (2 t = T)
R = V T cos θ horizontal range
3/4 g T^2 = V T cos θ 6 H = R given in problem
cos θ = 3 g T / (4 V) (I)
Now t = V sin θ / g time for projectile to fall from max height
T = 2 V sin θ / g
T / V = 2 sin θ / g
cos θ = 3 g / 4 (T / V) from (I)
cos θ = 3 g / 4 * 2 sin V / g = 6 / 4 sin θ
tan θ = 2/3
θ = 33.7 deg
As a check- let V = 100 m/s
Vx = 100 cos 33.7 = 83,2
Vy = 100 sin 33,7 = 55.5
T = 2 * 55.5 / 9.8 = 11.3 sec
H = 1/2 * 9.8 * (11.3 / 2)^2 = 156
R = 83.2 * 11.3 = 932
R / H = 932 / 156 = 5.97 6 within rounding

Answer:
The five components of physical fitness are cardiovascular endurance, muscular strength, muscular endurance, flexibility and body composition, according to Fit Day.
cardiovascular endurance:
Cardiorespiratory endurance:
is the level at which your heart, lungs, and muscles work together when you're exercising for an extended period of time. This shows how efficiently your cardiorespiratory system functions, and is an indicator of how physically fit and healthy you are.
muscular strength:
Muscular strength is defined as the maximum amount of force that a muscle can exert against some form of resistance in a single effort.
muscular endurance:
Muscular endurance is the ability of your muscle or muscle groups to withstand repeated contractions for an extended period.
flexibility and body composition:
Stretching before and after activities will help to improve flexibility. The sit-and-reach and the trunk lift are two tests used to measure flexibility. Body Composition is the percentage of body weight that is fat compared to other body tissue, such as bone and muscle.
