A 20 g lead bullet at a temperature of 50Ā°C and moving at a speed of 400 m/s strikes a large block of ice at 0Ā°C and stops inside it. How much ice melts?
Added by Cassandra C.
Step 1
First, we need to find the heat gained by the ice, which is equal to the heat lost by the bullet. To do this, we need to find the initial kinetic energy of the bullet and the heat lost due to the change in temperature of the bullet. Show moreā¦

A 20.0 -g lead bullet leaves a rifle at a temperature of $47.0^{\circ} \mathrm{C}$ and travels at a velocity of $5.00 \times 10^{2} \mathrm{m} / \mathrm{s}$ until it hits a large block of ice at $0^{\circ} \mathrm{C}$ and comes to rest within it. How much ice will melt?
A 20.0 g lead bullet leaves a rifle at a temperature of $47.0^{\circ} \mathrm{C}$ and travels at a speed of $5.00 \times 10^{2} \mathrm{m} / \mathrm{s}$ until it hits a $6.0 \mathrm{kg}$ block of ice at $0^{\circ} \mathrm{C}$ that is initially at rest on a frictionless surface. The bullet becomes embedded in the ice. (a) How fast is the the block of ice moving after the bullet is embedded? (b) How much ice melts?
