🤓 Based on our data, we think this question is relevant for Professor Goolsby Cole's class at UMBC.

# Solution: An important quantity to know during an inelastic is known as the  coefficient of restitution, which essentially measures how "ellastic" a collision is. The coefficient of restitution, e, is defined as  e = ( v1,f - v2,f ) / ( v1,i - v2,i ) where the v's are speeds, not velocities. If a ball were to drop from a height of 5 m, and only bounce up to a height of 4 m, what is the coefficient of restitution for the collision between the ball and the floor?

An important quantity to know during an inelastic is known as the  coefficient of restitution, which essentially measures how "ellastic" a collision is. The coefficient of restitution, e, is defined as

e = ( v1,f - v2,f ) / ( v1,i - v2,i )

where the v's are speeds, not velocities. If a ball were to drop from a height of 5 m, and only bounce up to a height of 4 m, what is the coefficient of restitution for the collision between the ball and the floor?
