Cool Physics with Classic Toys!
The law of conservation of momentum states that the momentum of an object before collision is equal to the combined momentum of the object and what it collides with after the collision. Therefore, let that tailgater collide with you and determine how fast they were traveling (never mind that their speed was close to yours or they wouldn't be tailgating).
Please be aware that this product was initially designed as a toy and has been modified to facilitate this lab.
