A 2m long pendulum with a mass of 250gr collides with a 95gr sticky ball seating in the pendulum's path and at the edge of a horizontal surface. The collision takes place while the pendulum is passing by its lowest point.
Note down that since each oscillator is attached to two "springs", and each "spring" is half the length of the interatomic bond, the effective interatomic spring stiffness for one of these oscillators is times estimated value given above.
A novice skier, starting from rest, slides down a frictionless 33.0° incline whose vertical height is 124 m. Explain how fast is she going when she reaches the bottom?
A metal block of mass m slides on a horizontal surface that has been lubricated with a heavy oil so that the block suffers a viscous resistance that varies as the 3/2 power of the speed F(v)=-cv^3/2. If the initial speed of the block is v0 at x=0,..
It compresses the spring, and then is pushed back in the opposite direction by the spring, eventually losing contact with the spring.
A hollow aluminium cylinder is to be fitted over a steel piston. At 22°C the inside diameter of the cylinder is 99.2 percent of the outside diameter of the piston. To what common temperature must the two pieces be heated in order that the cylinder ju..
