Photons of wavelength 220nm impact on a metal target and liberate electrons with kinetic energies ranging from 0 to 61X10 to the -20 power J. Determine the cutoff wavelength.
A billiard ball moving at 6.00 m/s strikes a stationary ball of the same mass. After the collision, the first ball moves at 5.12 m/s at an angle of 31.5° with respect to the original line of motion. find the struck ball's velocity after the collisi..
A 54.00 kg pole vaulter running at 10 m/s vaults over the bar. Her speed while she is above the bar is 1.0 m/s. Avoid air resistance, in addition to any energy absorbed by the pole, and determine her altitude as she crosses the bar.
