1. A spaceship with rest mass m0 is traveling with an x-velocity V0x=+4/5 in the frame of the earth. it collides with a photon torpedo (an intense burst of light) moving in the -x direction relative to the earth. assume that the ship's shield totally absorbs the photon torpedo.
a) the oncoming torpedo is measured by terrified observers on the ship to have an energy of 0.75m0. what is the energy of the photon torpedo in the frame of earth?
b) use convervation of four-momentum to determine the final x-velocity (in the earth frame) and mass (in terms of m0) of the damaged ship after it absorbs the torpedo. use an energy-momentum diagram to solve this problem graphically.
After a 0.800 nm x-ray photon scatters from a free electron, the electron recoils with a speed equal to 1.32E+6 m/s. Through what angle was the photon scattered
A parallel plate capacitor has a charge on one plate of q = 1.3E-06 C. Each square plate is d1 = 2.2 cm wide and the plates of the capacitor are separated by d2 = 0.65 mm, What is the voltage between the plates
How far does the object compress the spring if same experiment is performed on the moon, where g = 1.63 m/s2 and air resistance is neglected.
How many revolutions does the ball make during its fall. Now assume that the ramp is frictionless, so that the ball slides instead of rolling. Through what horizontal distance d does the ball move before landing in this case.
