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?

This is the start of a new topic (Dynamics 2: Motion on a Plane) and I don't know how to start the problem

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
