- Homework Statement
- A 0,47 g lead bullet moving at 151 m/s is stopped in a block of wood. All of the kinetic energy goes into heat energy added to the bullet. The initial temperature of the bullet is 32 degrees C. What is the final temperature of the bullet in degrees Celsius. The specific heat of the bullet is 130 and the mass of the wooden block is 5 g
- Relevant Equations
- Mv^2/2
I think that the kinetic energy is equal to heat right. Mv^2 / 2 = ms delta T
Delta T is 0,64
But I don’t really know if the temperature decreases or increases at the end
