A ball with v0 = 15 m/s collides with two identical balls which are lined up vertically as in the diagram below. The incoming ball is aimed directly at the contact point between the two balls. The collision is elastic, and there are no external forces acting. Find the velocities of all three balls after the collision.
An air-track glider is attached to a spring. The glider is pulled to the right and released from rest at t=0 s. What is the amplitude of the oscillation
A hydrogen atom consists of a single proton and a single electron. Experimentally it is found that it takes 13.6eV of energy to strip the electron from the proton. calculate the size of the hydrogen atom
Two sinusoidal waves of the same period, with amplitudes of 4.0 and 6.0 mm, travel in the same direction along a stretched string; they produce a resultant wave with an amplitude of 9.225 mm. The phase constant of the 4.0 mm wave is 0. What is the..
A certain star is 14 million light-years from Earth. The intensity of the light that reaches Earth from the star is 4.00 x 10-21 W/m2. At what rate does the star radiate EM energy.
