Answer:
The average force that the shooter must exert to prevent the weapon from moving is 21.7 Newtons.
Explanation:
m=33g=0,033kg
V= 342 m/seg
115 bullets/min= 1 bullet every 0.52 seconds.
By the principle of momentum and amount of movement we have to:
F*t=m*V
F= (m*V)/t
F= (0.033kg * 342 m/s) / 0.52 sec
F= 21.7 Newtons
I am pretty sure the answer is transformed or converted.
Answer:
Graph 1: This design does not control for distance from the central patch.
Graph 2: This design does not control for area of the patch.
Graph 3: In this design, there is no difference between the treatments.
Graph 4: This design does not control for edge effects.

Answer:
no
Explanation:
a constant speed = speed stays the same
accelerating = speed is increasing
Answer:
The force exerted by the muscle is 852.27N
Explanation:
Force F exerted by the muscle is expressed as a function of the torque τ and the effective perpendicular arm r.
F = τ/r ... (1)
Where τ = moment of inertia I × angular acceleration α
τ = Iα ... (2)
Substituting equation 2 into 1 to get F will give;
F = Iα/r
Given the following parameters
I = 0.75kgm²
α = 37.5rad/s²
r = 3.30cm = 0.033m
F = 0.75(37.5)/0.033
F = 28.125/0.033
F = 852.27N
The force exerted by the muscle is 852.27N
