Asked by Iries Gonzales
A lead bullet is traveling at 200 m/s strikes a tree and comes to stop. If half of the heat produced is retained by the bullet, by how much does the temperature increase?

heat energy gained = kinetic energy
m x c x t = K.E.
m x c x t = 1/2 x m x v x v
c x t = 1/2 x v x v
t = (1/2 x v x v)/c
t = (1/2 x 200 x 200)/150 (since, shc = 150 J/kgC)
t = 20000/150
t = 133.33 c
m x c x t = K.E.
m x c x t = 1/2 x m x v x v
c x t = 1/2 x v x v
t = (1/2 x v x v)/c
t = (1/2 x 200 x 200)/150 (since, shc = 150 J/kgC)
t = 20000/150
t = 133.33 c
