Q. Consider two simple pendulums p and q of equal length l and mass m1 and m2 respectively.suppose the bobs of the pendulum are connected to each other by a weightless spring of force constant k such that in the equilibrium position,the spring is unstretched.calculate the normal mode frequencies and draw a labelled diagram corresponding to each mode.
What is your displacement after running 2 {rm km} on Strawberry Fields, 1.6 {rm km} on Penny Lane, and 4.8 {rm km} on Abbey Road.
Two trains, each having a speed of 38 km/h, are headed at each other on the identical straight track. A bird that can fly 70 km/h flies off the front of one train while they are 68 km apart and heads directly for the other train. On reaching other tr..
A string is wrapped around the disk of mass m = 1.8 kg and radius R = 0.11 m. Starting from rest, you pull the string with a constant force F = 8 N along the nearly frictionless surface. At an instant when the center of the disk has moved a distan..
