Consider an elastic collision in one dimension that involves objects of mass 2.5 kilogram and 4.5 kilogram. The larger the mass is initially at rest, and the smaller one has an initial velocity of 12 m per sec. Calculate the final velocities of the two objects after the collision.
The prong of a tuning fork moves back and forth when it is set into vibration. find the maximum velocity and the maximum acceleration of the prong
An undamped oscillator has period 0 = 1.000 seconds, but I now add a little damping so that its period changes to 1 = 1.001 seconds. What is the damping factor ? By what factor would the amplitude of oscillation decrease after 10 cycles.
