Horizontal Projectile Motion

If the motion in the x-direction is a constant velocity, what is the acceleration in that direction?

What is the initial velocity of the ball in the y direction before it is dropped?

• Negative 9.81 meters per second squared

• 10 miles per hour

• 4.469 meters per second

• 0 meters per second

What should you solve for first?

Which equation is used to calculate the time taken for the ball to fall in the y direction?

• Displacement equals velocity times time

• Acceleration equals velocity divided by time

• Change in position equals initial velocity times time plus half acceleration times time squared

• Velocity equals displacement divided by time

How is the displacement in the x direction calculated?

• By multiplying velocity in the x direction by time

• By subtracting velocity in the x direction from time

• By dividing velocity in the x direction by time

• By adding velocity in the x direction to time

What factor had the largest impact on the precision of the experiment?

• Air resistance

• Speed of the car

• Height of the ball

• Bucket size
