Answer:
B equilibrium
Explanation:
The feedback mechanism is used to sense, monitor, restore and maintain a system. It can sense when a system is not at equilibrium, thereby tries to restore the equilibrium by negating changes.
So, The feedback mechanism tries to negate changes to restore the equilibrium of a system
The formula for impulse is F*(t₂-t₁)=m*(v₂-v₁), where F is the force, t is time, m is mass and v is velocity.
In our case m*(v₂-v₁)=16 N s, m=4 kg, v₁=0 and t₁=0.
m*(v₂-0)=16 N s, we solve for v₂:
4*v₂= 16
v₂=16/4
v₂=4 m/s
So the final velocity of the ball is v₂=4 m/s.
Given that,
Force F= 30,000 N
mass m= 4000 kg
acceleration = ?
since,
F= ma
a= F/m
a= 30,000/4000
a= 7.5 m/s²
acceleration of the given aeroplane will be 7.5 m/s².
