Velocity: What is it? Velocity is a speed in a specific direction. Formula: v= d/t + direction Examples of velocities: 30 m/s to the left 45 mi/hr west 18 km/s up
Velocity Example Problems 1. Tim was taking a rocket ship to his home in outerspace. If the rocket travels 900 km in 2 minutes towards the sun, what is his velocity? 2. Bobbi is driving North to her grandparents’ home in Ohio. If she drives 720 km for 12 hours, what is her velocity?
REMEMBER!!!!!!! Solve Velocity problems JUST LIKE SPEED problems. Just add in a DIRECTION.
