20. A tricycle wheel of radius 0.11 m is at rest and is then accelerated at a rate of 2.3 rad/s2for a period of 8.6 s. What is the wheel’s final angular velocity? w = wo + at -> w = 0 + 2.3 ( 8.6) = 19.78 -> 20 rads/s

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.
