Potential Energy
Scientists wish to understand how the new torpedo bats being used in the MLB affect the velocity of a baseball. To measure this, they have a player hit 100 baseballs with this new bat style and measure the exit velocity of the baseball.
In this experiment, what is the system and what are the System and Surroundings
System - Baseball
Surroundings - Everything but the baseball :)

A sled is at the top of a snowy hill with 4,900 joules of potential energy. It slides down the hill, and all of that potential energy is converted into kinetic energy by the time it reaches the bottom (ignore friction and air resistance). If the sled is moving at a velocity of 10 m/s at the bottom of the hill, what is the mass of the sled?
98kg
