Aski jumper travels down a slope and
leaves the ski track moving in the horizon-
tal direction with a speed of 30 m/s as in the
figure. the landing incline below her falls off
with a slope of = 48º.
the acceleration of gravity is 9.8 m/s².
30 m/s

Taylor's experiment: 1. accurately measured the speed of light 2. locked together the phases of two light sources so that the interference pattern would not shift 3. showed that man's reaction time was much slower than the speed of light 4. showed that individual photons have wave characteristics

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.
