With the changes, does this look correct?
Mass= 700kg x 4=2800kg
Specific heat capacity of steel= 0.42kJ/kgC
heat=70000kJ
change in temp= temp final- temp initial
temp initial=-250C
change in temp= (70000)/(2800 x 0.42)=59.5C
Temp final - temp initial= 59.5C
Temp final - (-250C)=59.5C
Temp...
Just started this topic so I'm not sure if this is the correct way to solve this, any help would be appreciated.
mass of object x change in temp x specific heat capacity= heat
change in temp= heat/(mass of object x specific heat capacity)
Mass= 700kg
Specific heat capacity of steel= 0.42kJ/kgC...
Usps=1/2(1.8x10^6)(0.03)^2=810J
Ke=1/2mv^2=1/2(0.05)(300)^2=2250J
I don't know how to take it farther than this, or if this is the correct way to start the problem. If this is correct, would it be correct to assume that the bullet does penetrate the creature because Ke overcomes Usps?
0.25g converts into 2.45m/s^2
V(t)=Vo+AoT
1=0+2.45T
T=1/2.45
T=0.4s
X(t)=VoT+1/2AoT
X(t)=100+0+1/2(2.45)(0.4)^2
X(t)=100.196m
I don't know if this is the right methodology or how to move on from here
