Answer:
Explanation:
If the distance () and speed (), measured in centimeters and centimeters per hour, respectively, are directly proportional to each other, then each set of values must observe the following relationship:
(Eq. 1)
Where is the proportionality constant, measured in .
If we know that , , , , and , then the constant of proportionality for each pair is:
As , we conclude that correct equation is .

Answer:
a=1.8 m/s^2
Explanation:
F=ma
So
a=F/m
Where F=1800 N, m=1000 kg
a=1800/1000
a=1.8m/s^2
Answer:
A. 54.88m/s.
B. 153.66m
Explanation:
Data obtained from the question include:
Time (t) = 5.6 secs
A. Determination of the skydiver's downward velocity.
Time (t) = 5.6 secs
Acceleration due to gravity (g) = 9.8m/s²
Velocity (v) =..?
v = gt
v = 9.8 x 5.6
v = 54.88m/s
Therefore, the skydiver's downward velocity is 54.88m/s
B. Determination of the height below the helicopter.
Time (t) = 5.6 secs
Acceleration due to gravity (g) = 9.8m/s²
Height (H) =..?
H = ½gt²
H = ½ x 9.8 x 5.6²
H = 153.66m
Therefore, the height below the helicopter when the parachute opens is 153.66m.
