Answer:small barrel gun
Explanation:
Given
Muzzle velocity of bullet is greater in short barrel gun as compared to larger barrel gun
acceleration is given by change in velocity with respect to time

In case of short barrel bullet time taken by bullet to reach its muzzle velocity is less therefore acceleration of small barrel bullet is more compared to long barrel bullet.
Answer:
10N
Explanation:
The formula for calculating the resultant is expressed as;
R = √F1²+F2²
F1 and F2 are the forces
Given
F1 = 6.0N
F2 = 8.0N
R = √6²+8²
R = √36+64
R = √100
R = 10.0N
Hence the magnitude of the net force is 10N
Answer: 13.33 m/s^2
Explanation:
Force is the product of mass of an object and its acceleration.
i.e Force = Mass x Acceleration
Since Force on object = 800N
Mass of object = 6Kg
Acceleration = ?
Then, Force = Mass x Acceleration
800N = 60Kg x Acceleration
Acceleration = (800N/60kg)
Acceleration = 13.33 m/s^2 (The unit of acceleration is metre per second square)
Thus, the objects accelerations is 13.33 m/s^2

Answer:
a) A = 0.603 m
, b) a = 165.8 m / s²
, c) F = 331.7 N
Explanation:
For this exercise we use the law of conservation of energy
Starting point before touching the spring
Em₀ = K = ½ m v²
End Point with fully compressed spring
=
= ½ k x²
Emo = 
½ m v² = ½ k x²
x = √(m / k) v
x = √ (2.00 / 550) 10.0
x = 0.603 m
This is the maximum compression corresponding to the range of motion
A = 0.603 m
b) Let's write Newton's second law at the point of maximum compression
F = m a
k x = ma
a = k / m x
a = 550 / 2.00 0.603
a = 165.8 m / s²
With direction to the right (positive)
c) The value of the elastic force, let's calculate
F = k x
F = 550 0.603
F = 331.65 N
