A 4.0g lead bullet travelling at 350m/s strikes a block of ice at 0°C. If all the heat generated goes into melting the ice, how much is melted? The latent heat of fusion of ice is 80Kcal/kg, and its specific heat is 0.50Kcal/kg.°C

Write the equation for momentum, first using symbols for the variables, then using words for the variables.

Tall pacific coast redwood trees can reach heights of about 100 m. if air drag is negligibly small, how fast is a sequola cone moving when it reaches the ground f it dropped from the top of a 100 m tree?

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?
