I’m pretty sure the answer would be : 
9.8m/s2
Explanation: gravity =9.8m/s2
        
             
        
        
        
Answer:
24°
Explanation:
sin(34°)/sin(x)=v2/v1
x=arcsin(2,1*sin(34°)/2,8)=24°
 
        
             
        
        
        
To look for the acceleration, it will come from:
vf^2=v0^2+2ad 
where:
vf = final velocity = 0 
v0 = initial velocity =251 m/s 
a = acceleration 
d= distance traveled = 0.237 m 
0=251^2+2a(0.237 ) 
a= -251 ^2 / (2*0.237) =-132 913.502 m/s/s 
we find the force from: 
F = ma = 0.0115kg*(-1.32x10^5m/s/s) = -1518 N 
the negative sign shows that the force is in the direction contradictory the
bullet's motion
 
        
             
        
        
        
So then they get warmed up and can be seen easily
