Q1. One closed organ pipe has a length of 2.55 m.
a) What is frequency of the note played by this pipe?
b) When a second pipe is played at the same time, a 1.30 Hz beat note is heard. By how much is the second pipe too long?
Q2. A 2.00-kg object travelling east at 20.0 m/s collides with a 3.00-kg object travelling west at 10.0 m/s. After the collision, the 2.00-kg object has a velocity 5.00 m/s to the west. How much kinetic energy was lost throughout the collision?
