Kinematics review

a car travels 50 meters east in 10 seconds what is the car's velocity?

• 5m/s

• 500m/s

• 25m/s east

• 5m/s east

A car travels at a constant velocity of 8 m/s for 10 seconds what is the acceleration?

• 80m/s/s

• 0.8m/s/s

• 0m/s/s

• 4m/s/s

acceleration is defined as:

• change in displacement

• rate of change in displacement

• change in velocity

• rate of change in velocity

The slope of the position time graph is

• distance

• velocity

• acceleration

• time

An object moving at 60 m/s takes 10 s to come to a stop . What is the object’s acceleration?

• 6m/s/s

• 60m/s/s

• -6m/s/s

• -60m/s/s

an object is dropped from a building of 200m how long does it take to reach the ground?

• 10.11s

• 6.38s

• 40.81s

• 200s

an object is launched 0° off a table at the same time an object is dropped from the same height. which hits the ground first?

• same time

• launched object

• dropped object

an object is launched at 40 m/s at a 30° angle what is the closest value of Initial velocity in the X direction(Vix)?

• 20m/s

• 40m/s

• 35m/s

• 0m/s

What is the difference between a vector and a scalar?

• scalar has direction when vectors do not

• scalar has direction and magnitude where a vector does not.

• vector has direction and magnitude where scalar does not.

• Nothing is different

an object is launched at 40 m/s at a 30° angle what is the closest value of initial velocity in the Y direction (Viy)?

• 20 m/s

• 35m/s

• 40m/s

• 0m/s
