You are playing Hot Rod toy cars with your nephew and niece. Your nephew wanted to show off how fast he could launch a Hot Rod off the dining table 1.0 m above the floor by thrusting the car forward very fast but was no match against your niece who compensated slight lack of speed by pushing the car straight forward reaching a speed of 4.5 m/s at the edge of the table top when she let go of it. What was the magnitude of the final speed when it hit the floor?
