2018 #5 Free Response Question - AP Physics 1 - Exam Solution

The video tutorial covers a physics problem from the 2018 AP Physics One exam, focusing on a mass-spring system. It explains the setup where block Q lands on block P, forming a new oscillating system. Part A involves calculating the period ratio of the new system to the original, while Part B compares the amplitudes before and after the collision. The tutorial discusses momentum and energy conservation principles, providing detailed solutions and emphasizing the importance of understanding physics concepts over pattern recognition in exams.

What is the initial setup of the problem involving blocks P and Q?

• Block P is on a frictionless surface and attached to a spring, while block Q is dropped onto it.

• Block P is on a rough surface and block Q is dropped onto it.

• Block P is on a frictionless surface and attached to a spring, while block Q is suspended above.

• Block P and Q are both on a frictionless surface, attached to separate springs.

How is the period of a mass-spring system calculated?

• 2π times the square root of the spring constant divided by mass.
