A roller-coaster car has a mass of 1170 kg when fully loaded with passengers. As the car passes over the top of a circular hill of radius 20 m, its speed is not changing.At the top of the hill, what i
Calculate the ratio of the drag force on a jet flying at 1140 km/h at an altitude of 10 km to the drag force on a prop-driven transport flying at half that speed and altitude. The density of air is 0.
Two gliders are moving on a horizontal frictionless air track. Glider 1 has mass m1 = 194.3 g and is moving to the right (positive x-direction) with speed 2.277 m/s. Glider 2 is moving to the left (ne
The electron-volt, eV, is a unit of energy (1eV = 1.602 ·10–19 J, 1 MeV = 1.602 ·10–13 J). Since the unit of momentum is an energy unit divided by a velocity unit,
In a classical harmonic oscillator, a particle with energy E moves (oscillates) in the "classically allowed region":\(|x| <= \sqrt{\frac{2E}{m\omega^{2}}}\) (less than or equal to) \(unde
A particle (M1 = 1.99 kg) moving at 30.0° downward from the horizontal with v1 = 2.25 m/s hits a second particle (M2 = 2.99 kg), which is at rest. After the collision, the speed of M1 is reduced t
The complex amplitudes of a monochromatic wave of wavelength "Lambda" in the z=0 and z=d planes are f(x,y) and g(x,y), respectively.Assuming that d = 10^4(Lambda), use harmonic analysis to determine g
The electron-volt, eV, is a unit of energy (1eV = 1.602 ·10-19 J, 1 MeV = 1.602 ·10-13 J).Since the unit of momentum is an energy unit divided by a velocity unit, nuclear physicists usua
Although they don't have mass, photons-traveling at the speed of light-have momentum. Space travel experts have thought of capitalizing on this fact by constructing solar sails-large sheets of materia
