The interaction that caused the archer to miss was probably refraction.
The train would need the greatest amount of force due to weight! If you think of it, a baseball won't need much force to stop it, but if you have a heavy train, it will need excessive force to stop the train. The answer would be #3
I hope this answer helps!
Sorry if it doesn't make sense, as I don't know that much about physics! I am just thinking of what makes sense.

Answer:
F= 175.5N
Explanation:
Given:
Torque which can also be called moment is defined as rotational equivalent of linear force. It is the product of the external force and perpendicular distance
torque of 38N⋅m
angle of 120∘
Torque(τ): 38Nm
position r relative to its axis of rotation: 25cm , if we convert to metre for consistency we have 0.25m
Angle: 120°
To find the Force, the torque equation will be required which is expressed below
τ = Frsinθ
We need to solve for F, if we rearrange the equation, we have the expression below
F= τ/rsinθ
Note: the torque is maximum when the angle is 90 degrees
But θ= 180-120=60
F= 38/0.25( sin(60) )
F= 175.5N
Answer:
a) 0.804second
b) 0.162m
Explanation:
In simple harmonic motion;
Period T = 2π√m/k
Where m is the mass of the object
K is the force constant
Given:
M = 13.0kg
K = 788N/m
T = 2π√13/788
T = 2π√0.0165
T = 2π×0.128
T = 0.804second
Frequency is the reciprocal of the period. F = 1/T
F = 1/0.804
F = 1.244Hertz
b) To get the amplitude x, we will use the relationship F = kx where F is the force exerted by the baby of mass 13kg
x = F/k
Since F = mg
x = mg/k
Assume g = 9.81m/s²
x = (13×9.81)/788
x = 127.53/788
x = 0.162m
The minimum amplitude that she requires is 0.162m
