Vf = vi + at 
0 = 150 m/s + a(0.03 s) 
a = -5000 m/s^2 

vf^2 = vi^2 + 2ad 
0 = (150 m/s)^2 + 2(-5000 m/s^2)(d) 
d = 2.25 m 

F = ma 
F = (0.01 kg)(5000 m/s^2) 
F = 50 N

V=u+at
0=150+a*0.03
-150/0.03=a
a=-5000m/s²

s=ut+1/2 at²
s=150*0.03-0.5*5000*0.03*0.03
s=4.5-2.25
s=2.25m
 The distance penetrated is 2.25m
