Answer:
<h2>E. 650N</h2>
Explanation:
step one:
given
length of stretcher= 2m
weight of stretcher=100N
Wayne weighs =800N
distance of Wayne weighs from chris's end= 75cm= 0.75m
The force that Chris is exerting to support the stretcher, with Wayne on it, can be computed by taking moments of the weight of the stretcher and Wayne weighs about Chris's end, the end result is the reaction at Chris's end
Taking moment about Chris's end
The moment of Wayne weight 75cm from Chris+ Half the weight of stretcher 1m from Chris
0.75*800+50*1=0
600+50=0
650N
It can hurt and harm the body on many different and levels

Answer:
1.10 m
Explanation:
First, find the time it takes to land.
Given, in the y direction:
Δy = 1.12 m
v₀ = 0 m/s
a = 9.8 m/s²
Find: t
Δy = v₀ t + ½ at²
(1.12 m) = (0 m/s) t + ½ (9.8 m/s²) t²
t = 0.478 s
Next, find the distance traveled in that time.
Given, in the x direction:
v₀ = 2.30 m/s
a = 0 m/s²
t = 0.478 s
Find: Δx
Δx = v₀ t + ½ at²
Δx = (2.30 m/s) (0.478 s) + ½ (0 m/s²) (0.478 s)²
Δx = 1.10 m
