2D Vectors and Motion

The scenario shown in the picture exists in warped physics world. Which of the following is true about the object that moves off the cliff? (select any that apply)

• The initial velocity in the y direction is 0m/s.

• The object will take more time to move in the path pictured than if it just fell off the cliff with no initial velocity.

• The only acceleration that exists on the object is the acceleration due to gravity.

• The final velocity when it hits the ground is 0 m/s.

Which of the following statements are true of the horizontal motion of a projectile launched at an angle of 25^o above the horizontal? Select all that apply.

• The horizontal velocity at the peak is the same as just after it was launched.

• The horizontal acceleration is 0 m/s^2.

• The horizontal velocity increases as the projectile falls downward from the peak.

• The horizontal velocity is 0m/s at the peak of the trajectory.

• The magnitude of the horizontal acceleration is 9.8 m/s².
