What is the total distance traveled by the car?

Jermaine runs exactly 2 laps around a 400 meter track. What is the displacement?

Speed of an object is equal to the magnitude of velocity if-

• the object is travelling in uniform circular motion

• the object is travelling along a straight path

• the initial and final positions are same

• none of these

Which term means speed with a direction?

• Speeding
• Acceleration
• Velocity
• Gravity

The force that opposes the motion of two surfaces that are in contact and are sliding over each other.

• Static Friction
• Kinetic Friction

Calculate the acceleration for segment A.

• 2 m/s²
• 20 m/s²
• -2 m/s²
• 0 m/s²
