What is the primary focus of kinematic equations in physics?

• Understanding the concept of force

• Analyzing motion with constant acceleration

• Solving problems involving two-dimensional motion

• Studying the effects of gravity

In the first problem, what is the initial velocity of the car?

• 5.15 meters per second

• 7.1 meters per second

• 8.1 meters per second

• 0 meters per second

Which kinematic equation is used to find displacement when initial and final velocities and time are known?

• Final velocity = initial velocity + acceleration × time

• Displacement = 1/2 × (initial velocity + final velocity) × time

• Displacement = initial velocity × time

• Acceleration = (final velocity - initial velocity) / time

What is the calculated displacement of the car in the first problem?

• 30 meters

• 29 meters

• 27 meters

• 28.755 meters

In the second problem, what is the acceleration of the car?

• 2.5 meters per second squared

• 2.75 meters per second squared

• 5.15 meters per second squared

• 7.1 meters per second squared

How do you calculate the final velocity in the second problem?

• Final velocity = initial velocity + time

• Final velocity = initial velocity + acceleration × time

• Final velocity = initial velocity × acceleration

• Final velocity = acceleration × time

What is the final velocity of the car in the second problem?

• 8.1 meters per second

• 5.15 meters per second

What is the correct kinematic equation to find time when initial and final velocities and acceleration are known?

• Time = acceleration / (final velocity - initial velocity)

• Time = initial velocity / acceleration

• Time = final velocity / acceleration

• Time = (final velocity - initial velocity) / acceleration

How long does it take for the car to reach its final velocity in the practice problem?

• 3.0 seconds

• 4.0 seconds

• 2.0 seconds

• 1.0 second
