A car is traveling West on Old Milton Parkway at 100 km/hr when the driver spots a police cruiser in the bushes. The driver hits the brakes and the velocity of the car is reduced to 80 km/hr. How would you describe the acceleration of the car and driver? (Assume east is the positive direction).

The car experienced negative acceleration with velocity in the positive direction.

The car experienced positive accelerationwith velocity in the negative direction

The car had negative acceleration with velocity in the positive direction

The car had positive acceleration with velocity in the negative direction

The rocket will need to decelerate rapidly

The rocket would have to have constant velocity for the entire trip.

The rocket must make the trip in at least 5 minutes

The rocket must accelerate until it is traveling 11.2 km/s, in at least 2000km.

3

The distance traveled is greater than the displacement.

The displacement is 6 km.

The distance traveled is 6 km.

The displacement is greater than the distance traveled.

3

Average speed is always less than average velocity.

Average speed is a vector quantity, but average velocity is a scalar quantity

Average speed has only magnitude, but average velocity has both magnitude and direction.

Average speed has units of mph and average velocity has units of m/s.
