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.
