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?

Q3. Murry stands at the edge of a merry-go-round. The ride has a radius of 3 m, and rotates once every 3.5 s. What is the least coefficient of friction to keep Murry from sliding off the ride?

What is the greatest velocity of this mass : A 4.70 kg mass causes a vertical spring to stretch 0.850 meters. The spring is after that stretch and extra 0.270 meters and release (as a stopwatch starts) causing the spring and mass to oscillate.

What is the tension in the string : It's found that string is set into oscillation only at the frequency 880 Hz and 1320 Hz as the frequency of an oscillator is varied over the range 500-1500 Hz. What is the tension in the string.
