Answer:
Force, 
Explanation:
Given that,
Mass of the bullet, m = 4.79 g = 0.00479 kg
Initial speed of the bullet, u = 642.3 m/s
Distance, d = 4.35 cm = 0.0435 m
To find,
The magnitude of force required to stop the bullet.
Solution,
The work energy theorem states that the work done is equal to the change in its kinetic energy. Its expression is given by :

Finally, it stops, v = 0



F = -22713.92 N

So, the magnitude of the force that stops the bullet is 
Answer:
e.26m/s
Explanation:
Vf=Vi+at (1)
Vf=9j+(2i-4j)t
X= X₀+at
now, in the i direction
15=O+2t or t=7.5 when x position is 15
Lets put that into the (1) equation, solve for Vf.
Vf=9j+(2i-4j)7.5
Vf= 15i - 21j
Speed=
Vf= 25.8 m/s

a) technician A
Explanation: A parking brake is a secondary and support brake system which is usually applied when the vehicle is not in motion,this is done to prevent any form of motion and the possibility of any form of accident.
A secondary circuit is a circuit or coil in which current is generated through induction from another circuit or coil called the primary circuit,it has not been discovered that a low pressure from that circuit has led to poor trailer parking brake performance.
I think it’s R=U/I = 120/5 = 24
