Dylan, Sarah, Joe 12/20/11 In order to find out if the SUV was speeding, we first had to find out the velocity of both the SUV and the wagon immediately following the collision. We found that the velocity of the SUV was 2.83 m/s and the wagon was 12.0 m/s. These values were found by using the kinematics equations to find Vi because we already had enough information to solve for the unknown in Vf^2=Vi^2+2ad.
Then, we could find the momentum of the wagon and SUV immediately af
