Answer:
a) F = 1.26 10⁵ N, b) F = 2.255 10³ N, c) F_ {soil} = 3078 N
Explanation:
For this exercise we will use the relationship between momentum and moment
I = Δp
F t = p_f -p₀
a) with stiff legs, final speed is zero, initial velocity is down
Ft = 0-p₀
F = m v / t
let's calculate
F = 84.0 6.82 / 4.56 10⁻³
F = 1.26 10⁵ N
b) bending the legs
let's calculate
F = 84.0 6.82 / 0.254
F = 2.255 10³ N
c) It is requested to calculate the force of the ground on the man
∑ F = F_soil -W
F_soil = F + W
F_ {soil} = 2.255 103 + 84 9.8
F_ {soil} = 3078 N
Alvin (DSV-2) is a manned deep-ocean research submersible owned by the United States Navy and operated by the Woods Hole Oceanographic Institution (WHOI) in Woods Hole, Massachusetts. The vehicle was built by General Mills' Electronics Group[2] in Minneapolis, Minnesota. Named to honor the prime mover and creative inspiration for the vehicle, Allyn Vine, Alvin was commissioned on 5 June 1964. The submersible is launched from the deep submergence support vessel RV Atlantis (AGOR-25), which is also owned by the U.S. Navy and operated by WHOI. The submersible has made more than 4,400 dives, carrying two scientists and a pilot, to observe the lifeforms that must cope with super-pressures

Explanation:
Answer:
When the y-coordinate is 12m, the x-coordinate of the particle is 24 m
Explanation:
Given;
y - component of acceleration = 1 m/s²
X - component of acceleration = 2 m/s²
distance traveled in y - direction, Dy = 12 m
To determine the distance traveled in X- direction, we obtain the duration of the displacement in y- direction.
Applying equation of motion;
Dy = ¹/₂ x at²

For distance traveled in x -direction;
Dx = ¹/₂ x at²
Dx = ¹/₂ x 2 x (4.9)² = 24.01 m ≅ 24m
Therefore, when the y-coordinate is 12m, the x-coordinate of the particle is 24 m
