Homework Statement
A 3.20 g lead bullet at 28.0°C is fired at a speed of 210 m/s into a large block of ice at 0°C, in which it becomes embedded. What mass of ice melts (g)?
Homework Equations
I thought that the KE of the bullet would be transferred into heat
The Attempt at a Solution
I used MV^2/2 = 0.0032x210^2/2
=70.56J
divided that by heat of fusion of ice, 80cal/g
=0.882g
Its wrong tho
someone pls help :) thanks.
