Find the velocity of a plane that traveled 3000 miles west in 5 hours.

• 65 mph west
• 6 mph west
• 600 mph west
• 6000 mph west 

Pick all of the following that are velocities.

• 4 km/s west

• 5 cm/h south

• 2 mph

• 8 cm/year

• 5 m/s up

When a car goes around a corner at 20 mph, why do we say it  accelerates?

• The car is accelerating because of the velocity is constant
• The car accelerates because it's going 20 mph
• Cars always accelerate when they are in motion
• The car is accelerating because it's changing direction

In each of the following cases, determine where the car has no acceleration ?

• A car shortly after a stoplight turns green.
• A car approaching a red light
• A car with the cruise control set at 80 km/h
• A car turning a curve at a constant speed
