In a ballistics test, a 25 g bullet traveling horizontally at 1200 m/s goes through a 45 cm thick 350 kg stationary target and emerges with a speed of 1000 m/s. The target is free to slide on a smooth horizontal surface.
(a) How long is the bullet in the target (assume constant
acceleration)?
s
What average force does it exert on the target?
N (magnitude only)
(b) What is the target's speed just after the bullet emerges?
Mass of the bullet = m1 = 25 g = 0.025 kg
Mas of the block = m2 = 350 kg
Initial speed of the bullet = V0 = 1200 m/s
Speed of the bullet after coming out of the block = V1 = 1000 m/s
Distance the bullet travels through the block = Thickness of the block = D = 45 cm = 0.45 m
Acceleration of the bullet = a
V12 = V02 + 2aD
(1000)2 = (1200)2 + 2a(0.45)
a = -488888.89 m/s2
Time period the bullet is in the target = T
V1 = V0 + aT
1000 = 1200 + (-488888.89)T
T = 4.09 x 10-4 sec
Magnitude of the average force the bullet exerts on the target = F
F = |m1a|
F = |(0.025)(-488888.89)|
F = 1.222 x 104 N
Speed of the block after the bullet emerges = V2
By conservation of linear momentum,
m1V0 = m1V1 + m2V2
(0.025)(1200) = (0.025)(1000) + (350)V2
V2 = 1.43 x 10-2 m/s
a) Time period the bullet is in the target = 4.09 x 10-4 sec
Magnitude of the average force the bullet exerts on the target = 1.222 x 104 N
b) Target's speed just after the bullet emerges = 1.43 x 10-2 m/s
