A 70.0-g object connected to a spring with a force constant of 25.0 N/m oscillates with an amplitude of 6.00 cm on a frictionless, horizontal surface. Find the total energy of the system
In February 1955, a paratrooper fell 365 meter from an airplane without being able to open his chute but happened to land in snow, Obtain the magnitude of the impulse on him from snow
a bb gun is fired at a cardboard box m2 1.85 kg on a frictionless surface. the bb has a mass of m1 0.044 kg and
A plane weighing 220kN (25 tons) lands on an aircraft carrier. The plane is moving horizontally at 67 m/s (150 mi/h) when its tail hook grabs hold of the arresting cables. The cables bring the plane to a stop in a distance of 84 m. How much work is..
The lifetime of a pi meson in its on frame of reference is2.6* 10^-8 sec. If the meson moves by a speed of .99c, a) what is the lifetime as gauged by an observer at rest on Earth? b) How high would a 100m mountain be gauged in the meson's frame of re..
A Van de Graaff accelerator is essentially a parallel plate capacitor. Such a machine is changed by an electrical potential of 2.5 x 10^6 volts. What is the energy density stored in the field
A 45.6-kg girl is standing on a 155-kg plank. Both originally at rest on a frozen lake that constitutes a frictionless, flat surface. The girl begins to walk along the plank at a constant velocity of 1.40 m/s relative to the plank. (a) What is the ve..
