2015 #4 Free Response Question - AP Physics 1 - Exam Solution

The video tutorial covers a physics problem from the 2015 AP Physics exam, involving two spheres released from the same height. Sphere A has no initial velocity, while Sphere B has an initial horizontal velocity. Despite different horizontal distances traveled, both spheres land simultaneously due to gravity being the only acting force. The tutorial includes drawing free body diagrams, graphing horizontal velocities, and explaining the physics behind the simultaneous landing.

Explain the initial conditions of spheres A and B when they are released.

Describe the forces acting on both spheres after they have taken half the time to reach the ground.

Why do both spheres reach the ground at the same time despite traveling different horizontal distances?

What is the significance of air resistance in this scenario?

How does the acceleration of the spheres in the Y direction affect their motion?
