Question
So far we have learned that the formula for Kinetic Energy is KE= 1/2mv2. However, for this lab, we would like to describe the motion of the objects using momentum. p=mv, instead of velocity. Using the two equations given, find a new formula for Kinetic Energy in terms of momentum not velocity.
Based on the picture, which one is the correct answer?
